Foreword 


IN  presenting  this  catalog  for  your  consideration,  we  wish  to  call  your  attention  to 
some  of  its  most   distinctive  features.     No   attempt  has  been   made  to  prepare  a 
complete  list  of  scientific  laboratory  apparatus  and  equipment  as  there  are  many 
highly  specialized  forms  of  equipment  to  which  only  occasional  reference  is  necessary. 
This  special  apparatus   is   covered   by   separate  pamphlets   which   are  available   at  all 
times.    We  have  attempted  to  list  all  forms  of  standard  equipment  as  well  as  those  of 
special  design,  for  which  there  is  a  moderately  general  demand. 

THIS  CATALOG  IS  A  COMPILATION  OF  EXCLUSIVELY  AMERICAN  MADE 

GOODS  AND  IS  A  TRIBUTE  TO  THE  PROGRESS  MADE  BY 

AMERICAN  MANUFACTURERS 

We  have  elected  to  prepare  a  fairly  complete  catalog  of  convenient  size,  rather 
than  an  encyclopedia  of  scientific  apparatus,  which  would  of  necessity  be  so  bulky  as 
to  be  unwieldy. 

In  the  selection  and  arrangement  of  .descriptive  data  and  illustrations,  we  have 
been  guided  by  the  requirements  of  those  who  may  have  occasion  to  use  the  catalog. 
We  have  made  an  attempt  to  simplify  the  work  of  ordering  our  merchandise,  wherever 
it  has  been  possible  to  do  so,  without  sacrificing  accuracy  or  necessary  information. 

Each  illustration  shows  either  a  standard  type  of  apparatus  or  a  characteristic 
feature  which  may  be  adapted  to  your  requirements. 

As  a  general  rule,  the  articles  described  in  this  catalog  are  carried  in  stock  for 
immediate  delivery.  Other  apparatus  can  be  promptly  secured  or  made  up  at  a 
reasonable  cost. 

Reference  to  other  catalogs  will  be  understood  by  us  and  the  specifications  cor- 
rectly interpreted. 

The  utmost  care  is  observed  in  checking  and  packing  goods  for  shipment,  and 
every  effort  is  made  to  avoid  breakage  in  transit.  All  claims  for  loss,  damage  or 
breakage  in  transit  should  be  promptly  filed  against  the  carrier.  We  will  assist  in 
every  way  possible,  the  adjustment  of  such  claims.  Any  complaints  will  be  promptly 
and  cheerfully  investigated  and  complete  satisfaction  is  assured. 

All  prices  are  based  upon  actual  market  conditions  and  are  subject  to  change 
without  notice.  Fluctuations  may  be  expected,  but  our  prices  will  be  consistent  with 
existing  conditions  over  which  we  have  no  control. 

The  cost  of  containers  and  packing  will  be  charged  at  cost.  Acid  bottles,  cases, 
^carboys  and  some  drums  are  extra  and  returnable  for  full  credit  at  our  store  or 
warehouse. 

Our  terms  of  payment  are  NET  CASH  30  days,  F.  O.  B.  Chicago. 

Where  no  definite  shipping  instructions  are  furnished  with  order,  we  will  use  our 
own  judgment,  and  ship  by  shortest  and  cheapest  route.  All  shipments  are  made  in 
compliance  with  Interstate  Commerce  Commission  regulations.  Parcel-post  shipments 
will  be  made  wherever  possible,  with  a  small  charge  for  insurance. 

Conditions  arising  out  of  the  war  require  our  customers  to  obtain  licenses  for 
the  purchase  of  ethyl  alcohol  and  certain  chemicals  classified  as  explosives.  Whenever 
such  materials  are  ordered,  it  is  imperative  that  certified  copies  of  license  accompany 
the  order,  as  shipments  cannot  be  made  until  such  certificates  are  received. 

Our  GLASS  BLOWING  DEPARTMENT  is  adequately  equipped  to  repair  and 
make  up  all  kinds  of  standard  and  special  apparatus,  either  plain,  graduated  or  ground. 

Our  BALANCE  and  INSTRUMENT  REPAIR  DEPARTMENT  has  been  or- 
ganized to  inspect  and  repair  any  imported  or  domestic  balances  and  instruments. 
We  take  great  pride  in  our  ability  to  render  this  service  and  guarantee  all  work  of  this 
nature. 

We  wish  to  thank  our  friends  and  customers  for  their  past  consideration  and  hope 
that  it  will  continue.  We  solicit  all  inquiries,  and  no  order  is  too  small  to  receive  ©ur 
most  careful  attention. 

Our  organization  has  been  planned  for  SERVICE.     It  is  at  your  disposal. 

Faithfully  yours, 

A.  DAIGGER  &  COMPANY.

1000  ACID  CARBOY  STAND.  A  very  useful  and  simple  device,  whereby  the 
carrying  and  tilting  of  carboys,  otherwise  a  difficult  and  dangerous 
operation,  becomes  easy  and  their  'contents  can  be  poured  out  with 
safety.  The  carrying  bars  are  clamped  to  the  carboy  by  means  of  two 
screw  bolts,  which  rest  on  the  cleats  of  the  box;  these  bars  are  of 
such  length  as  to  project  beyond  the  end  of  the  box  and  provide 
handles  for  carrying.  The  stand  can  be  folded  up  in  a  compact 
manner  for  transportation $6.50

FOR  DETERMINATION  OF  ALCOHOL  IN 
BEVERAGES 


ACCORDING  TO  FRITZ 

This  apparatus,  known  also  as  the  NERBEROMETER,  was  especially  designed 
for  the  brewers  and  manufacturers  of  beverages  and  so-called  "near"  beers  for  the 
determination  of  alcohol  content.  This  apparatus  is  recommended  at  this  time  when 
so  many  substitutes  for  beer  are  being  produced  on  a  large  scale.  We  are  prepared 
to  furnish  this  apparatus  complete  from  stock,  as  well  as  the  separate  items  which 
make  up  the  apparatus  complete.  The  necessity  for  this  apparatus  has  been  brought 
about  by  the  stringent  requirements  of  the  law,  limiting  the  percentage  of  alcohol 
which  these  beverages  (so-called  "near"  beers)  are  permitted  to  contain. 


1011 

The  apparatus  consists  of  a  specially  constructed  copper  still,  gas  heated,  with  a 
copper  condenser,  water  cooled.  Under  proper  heat  control,  the  distillate  is  collected 
in  the  cylinder  as  shown  above.  An  aliquot  portion  is  withdrawn  and  the  percentage 
of  alcohol  read  with  an  alcoholometer.  The  still  and  condenser  are  made  of  heavy 
copper,  water  inlet  and  outlet  on  the  condenser  being  made  of  lead  pipe.  All  joints 
are  provided  with  rubber  gaskets. 

1011     Price  complete  as  shown $40.00 

For  prices  on  all  parts  which  are  interchangeable,  as  flasks,  pipettes,  burners, 
rubber  tubing  for  gas  and  water,  thermometers  and  so  forth,  \  see  under  alphabetical 
classification  throughout  the  catalog. 


While  it  is  impracticable  to  list  all  special  apparatus  required  for 
testing  materials,  we  wish  to  call  your  attention  to  our  special  sec- 
tions on  Tar  and  Asphalt  testing. 

We  are  prepared  to  furnish  any  apparatus  both  in  Metalware 
and  Glassware  required  on  special  tests,  etc.

HOYT'S  ELECTRICAL  PENETROMETER 

1072  HOYT'S — An   electrically  operated,   automatic   instrument   for   determining   the 

consistency  of  asphalt  and  similar  substances  by  measuring  the  depth 
to  which  a  standard  needle  with  a  definite  load  will  penetrate  during 
a  definite  period  of  time,  at  a  given  temperature. 

FOR  THE  STANDARD  TEST  THE  LEFT  PUSH  BUTTON  IS  PRESSED. 
This  releases  the  needle  with  attached  weight  and  penetration  instantly  takes  place. 
After  a  lapse  of  exactly  five  seconds  the  needle  is  automatically  reclamped  and  penetra- 
tion ceases.  The  depth  of  penetration  is  read  directly  from  the  dial,  each  division  of 
which  corresponds  to  0.1  mm.  downward  movement  of  the  needle. 

FOR  SPECIAL  TESTS  the  instrument  may  be  adjusted  for  any  variation  desired. 
Either  the  50,  100,  150,  200,  250,  300  or  350  gram  test  may  be  made  with  equal  accuracy 
and  speed  by  a  simple  substitution  of  weights.  The  needle  may  be  readily  clamped  or 
released  for  special  tests  by  means  of  a  clutch.  For  periods  of  penetration  other  than 
five  seconds,  the  push  button  on  the  right  may  be  used  and  any  desired  time  may  be 
allowed  for  penetration,  the  period  being  controlled  by  the  large  minute  dial  at  the  top 
of  the  instrument. 

DESCRIPTION — The  entire  instrument  is  automatic  and  is  operated  by  two 
ordinary  dry  cells.  It  is  enclosed  in  a  mahogany  case  with  glass  sash,  lock  and  key. 
There  is  also  a  large  drawer  located  in  the  base  for  keeping  the  testing  pans,  ther- 
mometer and  other  accessories. 

•  ADVANTAGES — 1st,  produces  uniform  penetration  tests;  2nd,  controls  the 
duration  of  tests;  3rd,  applies  uniformity  of  penetration  weights;  4th,  eliminates  vibra- 
tion during  operation;  5th,  insures  absence  of  personal  equation.

SAMPLING  OF  CREOSOTE  OIL  IN  TANK  CARS  AND  STORAGE  TANKS  FOR 
MAKING  WATER   DETERMINATIONS 

"It  is  recommended  as  good  practice  that,  in  order  to  obtain  accurate  determinations 
as  to  the  percentage  of  water  contained  in  creosote  oil  in  tank  cars  and  in  storage 
tanks,  the  principle  of  zone  sampling  be  employed,  and  described  in  the  1916  report 
of  your  Committee  (Proceedings,  Vol.  17,  pp.  447  to  456)  and  that  for  the  purpose  of 
obtaining  zone  samples  an  apparatus  of  the  type  illustrated  in  this  report  be  used." 

From  Bulletin  of  the  American  Railway  Engineering  Association,  Vol.  18,  No.  195, 
March,  1917. 

This  apparatus  consists  of  a  brass  cylinder  with  a  pointed,  perforated  bottom. 
The  holes  in  the  bottom  are  closed  by  means  of  a  spring  valve,  which  can  be  opened 
by  means  of  a  wire  extending  along  the  extended  stem  attached  to  the  cylinder. 
This  stem  is  made  in  several  sections,  so  that  it  can  be  used  at  any  depth.  The  stein 
is  calibrated  in  feet  and  inches,  thus  facilitating  the  zone  sampling.  The  apparatus  is 
as  illustrated.

Length  of  Beam   7  inches 

Bearings Agate  planes 

Knife   edges    •  • Agate 

Capacity  of  bar  and  vernier .  .50  Mgm.  to  1/10  Mgm. 

It  is  the  regular  No.  1105  Becker  Balance  equipped  with  chain,  and  gives  direct 
rapid  reading  without  rider  or  small  weights. 

Polished  mahogany  case,  front  sliding  frame,  counterpoised.  Mounted  on  black 
plate  glass. 

After  all  the  necessary  large  weights  up  to  50  milligrams  are  placed  on  the  pan, 
the  weighing  from  50  milligrams  to  1/10  of  a  milligram  can  be  concluded  without 
opening  the  balance  or  using  the  arrest,  eliminating  the  necessity  of  reading  and  re- 
placing all  small  weights  or  the  handling  of  a  rider  with  a  consequent  enormous  saving 
of  time. 

One  end  of  the  weighing  chain  is  hung  from  an  arm  of  the  scale  beam,  and  the 
other  end  from  a  slide-block  which  is  moved  up  and  down  on  a  vertical  graduated 
scale.  As  this  block  is  raised,  more  of  the  weight  of  the  chain  is  taken  from  the 
beam  and  hangs  from  the  slide-block  which  forms  a  stationary  support  for  holding 
the  inactive  part  of  the  chain.  As  the  slide  is  lowered  a  greater  proportion  of  the 
weight  of  the  chain  is  transferred  to  the  beam. 

Price $175.00

BALANCE,  SPECIFIC  GRAVITY.  Jolly  Spiral  Spring.  Mirror  Scale. 
This  balance  is  a  decided  improvement  over  the  general  style  of  appa- 
ratus of  this  kind,  being  made  of  metal  throughout  and  handsomely 
finished.  It  consists  of  an  upright,  3  feet  high,  supported  by  a  tripod 
base  fitted  with  leveling  screws.  The  stage,  scale  and  hook  are  clamped 
to  the  upright,  all  three  being  adjustable  separately.  The  improved 
mirror  scale  is  graduated  in  millimeters.  The  pans  are  of  aluminum 
suspended  on  very  sensitive  springs.  Two  springs,  a  high  and  low  ten- 
sion, are  included  with  each  balance $25.00 

Used    for    determining    specific    gravity    of    minerals,    etc.,    and    in    laboratories    of 
rubber  factories. 

1187    IMPROVED  CELERITAS  TRIPLE  BEAM  LABORATORY  BALANCE. 

This  balance  is  one  of  the  most  popular  of  our  specialties.  It  has  a 
capacity  of  111  grams,  a  sensibility  of  0.01  gram,  and  reads  directly  on 
the  aluminum  beam  to  0.01  gram.  The  beam  is  engine  divided  and  is 
tested  and  adjusted  at  each  division.  The  two  lower  weights  are  sup- 
plied with  spring  clips  to  insure  accurate  setting.  The  weights  do  not 
interfere,  and  they  are  attached  to  the  beam  so  that  they  cannot  be 
lost.  A  milled  head  lifts  the  center  knife  edge  from  its  bearing  when 
not  in  use.  The  stand  is  neatly  enameled  and  is  supplied  with  a  leveling 
screw,  spirit  level,  and  swinging  support  for  specific  gravity  work.  The 
pan  is  movable  and  its  hanger  has  an  extra  hook  for  specific  gravity $17.50

Owing  to  the  present  regulation  of  platinum  consumption  by  the  Gov- 
ernment officials,  we  have  discontinued  the  furnishing  of  platinum  fractions 
almost  entirely.  In  the  place  of  fractional  weights  made  of  platinum  we  are 
now  supplying  these  made  of  Gold,  Rhotanium  and  other  non-oxidizing 
metals.  These  weights  have  been  tested  very  carefully  and  found  to  be  ex- 
tremely accurate.  We  recommend  them  to  be  equal  in  every  respect  to  the 
platinum  fractional  weights.

PYREX  BEAKERS 

The  manufacturers  of  Pyrex  Glass  have  developed  a  low  expansion  bOrosilicate 
glass  possessing  a  combination  of  qualities  which  render  it  superior  in  many  respects 
to  any  glass  of  similar  type  heretofore  available. 

Composition 

The  simple  chemical  composition  of  the  glass  is  an  advantage  as  regards  possible 
contamination  of  liquids  in  contact  with  it.  It  contains  no  metals  of  the  magnesia- 
lime-zinc  group  and  no  heavy  metals.

1593     BLOWERS,  Crowell's  Rotary  Compressor  or  Vacuum  Pump,  Type  "D."     The 

Crowell  Type  "D"  Rotary  Air  Compressors  are  manufactured  in 
nine  standard  sizes  of  from  four  to  three  hundred  and  ninety  cubic 
feet  free  air  per  minute  capacities  and  are  designed  for  a  working 
pressure  of  twenty-five  pounds  or  less  per  square  inch.  When  usec* 
as  Vacuum  Pumps,  all  sizes  of  this  type  will,  under  permissible 
atmospheric  conditions,  exhaust  to  a  vacuum  of  from  twenty-nine 
to  thirty  inches  (mercury  column).  The  action  is  simple,  positive 
and  durable  with  a  continuous  intake  and  delivery  of  the  air.  No 
valves,  springs,  gears  or  unbalanced  parts  are  used  or  required  in 
the  construction.  The  pressure  or  degree  of  vacuum  is  not  de- 
pendent upon  high  operating  speeds  and  as  no  special  foundation  or 
great  amount  of  floor  space  is  required,  the  installation  and  onera-

tion  is  a  comparatively  simple  matter.  The  Crowell  system  of  lubrication  as  applied 
to  all  standard  Type  "D"  sizes,  is  positive  and  automatically  controlled  by  the  air 
pressure  or  vacuum.  The  oil  feed  valves  are  adjustable  to  suit  the  grade  of  lubricant 
used,  and  can  be  closed  entirely  when  necessary.  Rotates  in  one  direction  only  either 
for  use  as  a  Compressor  or  a  Vacuum  Pump,  requiring  no  changes  in  the  lubricating 
system  which  operates  from  the  outlet  or  pressure  side  under  either  compression  or 
vacuum.  Connections  should  be  made  to  the  inlet  or  suction  side  for  vacuum  work 
and  it  is  also  advisable,  when  using  as  a  compressor,  to  run  a  pipe  from  the  inlet  to 
such  place  where  a  clean  supply  of  air  is  assured.  The  heads  are  provided  with  water 
jackets  for  cooling,  when  necessary.  The  flow  of  water  is  regulated  by  the  valve 
which  is  fitted  to  the  overflow  or  discharge  pipe.  "Crowell  Rotaries"  are  also  made  in 
other  types,  special  sizes,  etc.,  for  lower  pressures  or  vacuums  as  well  as  for  higher 
pressures  up  to  125  Ibs.  to  square  inch,  or  practically  absolute  vacuums.  Plain  or 
automatically  controlled  motor  driven  outfits  supplied  in  all  types.

2133c  BURNER,  Boekel's,  for  burning  gases  of  various  qualities. 

By  turning  the  knurled  part  A,  you  can  increase  or  lower  the 
flame,  the  flow  of  gas  and  air  being  regulated  automatically,  and 
therefore  the  burner  will  always  retain  a  blue  flame. 

B  is  the  set-screw  by  which  to  regulate  the  burner-tip  C,  sup- 
plying more  or  less  air,  according  to  the  quality  of  gas.  The 
supply  of  air  is  regulated  by  inserting  the  screw  into  the  next 
slot,  either  to  the  right  or  to  the  left.  This  is  the  best  self- 
adjusting  Bunsen  burner  made,  and  we  can  recommend  it  to 
give  entire  satisfaction.  Height,  6  inches;  diameter  of  tube,  l/2

CALORIMETERS 


2176 


2176    CALORIMETER,  Standard— Parr's. 

This  instrument  has  been  devised  by  S.  W.  Parr,  professor  of  Applied  Chem- 
istry at  the  University  of  Illinois.  The  marked  features  of  the  method  are  accu- 
racy, simplicity,  ease  and  rapidity  of  manipulation.  The  results  are  absolute  and 
not  relative.  The  operations  are  such  as  can  be  carried  on  by  one  not  especially 
skilled  in  laboratory  processes.  Oxygen  under  high  pressure  or  any  pressure  is 
not  used.  Sodium  peroxide  is  used  as  the  combustion  medium. 

The  time  consumed  in  conducting  a  test  on  a  weighed  and  dried  sample 
should  not  exceed  fifteen  or  twenty  minutes.  With  this  instrument  a  determina- 
tion of  the  heat  units  has  been  made  on  the  various  types  of  fuel  selected  from 
widely  different  sources,  including  coal,  coke,  lignite  and  oils. 

The  outfit  consists  of  the  apparatus  as  indicated  in  cut,  including  a  fine 
thermometer  graduated  to  1/20°  F.  A  two-litre  measuring  flask,  chemical  recep- 
tacle, measuring  cup,  5-inch  100-mesh  brass  sieve  with  bottom,  chemicals  suffi- 
cient for  fifty  determinations,  including  special  chemical  for  petroleum,  etc., 
pincers,  ignition  wire,  reading  lens  and  camel's-hair  brush.

2177— PARR'S  NEW  PEROXIDE  CALORIMETER  BOMB. 


A  new  and  greatly  improved  form  of  bomb  for  the  Parr 
Standard  Calorimeter  has  been  devised  which  has  marked 
advantages  over  the  old  pattern.  A  summarized  statement 
of  advantages  for  more  convenient  reference  is  given  below: 

1.  A  removable  fusion  cup,  or  crucible,  is  provided  with 
an  extra  cup  for  duplicating  determinations.     These  cups  are 
made  of  a  special  alloy  which  is  immune  to  the  action  of 
the  fused  alkali.    The  materials  making  up  the  charge  can  be 
weighed  out  and  added  directly  to  the  cups,  which  may  then 
be  transferred  to  the  holders  for  use  as  desired. 

2.  The  electric  terminals  are  short  and  sturdy,  and  do 
not  become  bent*  or  broken  by  use. 

3.  Provision  is  made  by  means  of  an  air  space  about  the 
fusion  cup  whereby  the  cup  is  permitted  to  come  to  a  red 
heat,  after  which  the  surrounding  water  is  brought  into  con- 
tact with  the  cup  for  quick  extraction  of  the  heat.    This  high 
temperature    throughout   the   mass   avoids   the   cooling   eect 
of  metallic  walls  which  are  in  contact  with  water,  thus  secur- 
ing a  complete  combustion  with  all  types  of  coals. 

4.  By  use   of  the   fusion   cups   a   removable   bottom   is 
avoided  and  the  process  of  cleaning  out  the  fusion  is  very 
much  expedited.     The  cups  are  short  enough  to  readily  go 
into  a  small  No.  3  or  No.  4  beaker  lying  flatwise,  in  which 
way  the  fusion  is  readily  dissolved  out  without  loss. 

5.  The  electric  contacts  are  simplified  and  made  much 
more  convenient. 

6.  A   simple  additional  accessory  makes  it  possible  to 
use  the  fusion  cups  for  sulphur  determinations  alone.    This  is 
without  doubt  the  ideal  method  for  making  a  determination 
of   sulphur  in   all   organic   compounds   and   especially  to   be 
recommended   for   use   in   determining   the   sulphur   in   coal.

2179     PARR'S  NEW  SULPHUR  BOMB. 


sac 


For  sulphur  determinations  which  are  to  be  made  inde- 
pendently of  the  calorimetric  process,  a  special  apparatus, 
as  shown  in  Fig.  2D,  has  been  devised.  An  adaptation 
has  been  made  of  the  same  fusion  cup  as  that  used  in  the 
calorimeter  bomb  (Fig.  2A).  By  reference  to  Fig.  2D,  it 
will  be  seen  that  the  fusion  cup  (2AC)  has  a  cover  (7AC) 
with  a  gasket  (27AC),  and  a  screw  cap  (5AC),  by  means 
of  which  the  container  is  tightly  sealed.  The  lower  half 
of  the  fusion  cup,  however,  is  exposed,  and  by  applying 
heat  to  the  bottom  of  the  cup  the  charge  is  readily  ignited. 
After  a  moment,  it  is  held  under  the  tap  for  cooling,  after 
which  the  cup  is  removed  and  the  fusion  dissolved  otft. 
In  this  way  the  solution  containing  all  of  the  sulphur  as 
sulphate  may  be  made  ready  for  precipitation  in  less  than 
five  minutes  and  with  no  possible  accession  of  sulphur  from  gas  flames  or  other  sources 
of  contamination. 

Results  obtained  by  this  method  are  believed  to  be  the  most  reliable  of  any,  and 
the  time  element  is  decidedly  to  its  advantage. 

,  For  organic  halogens,  to  replace  the  ordinary  Carius  method  in  the  determination 
of  chlorine,  bromide  and  iodine,  the  use  of  this  bomb  will  be  found  exceedingly  con- 
venient and  expeditious.

The  method  of  holding 
the  bomb  in  place  for  screw- 
ing on  the  cap  and  admitting

2181     CALORIMETER— Parr's,  Oxygen  Bomb  Calorimeter  with  "Illium"  Bomb. 

Not  the  lease  among  the  achievements  in  the  construction  of  oxygen  bombs 
of  the  Mahler-Atwater  type  is  the  doing  away  with  the  porcelain  or  platinum 
lining  as  a  result  of  the  development  of  an  alloy  which  is  proof  against  the 
solvent  action  of  the  acids  generated  in  connection  with  the  combustions. 

The  first  successful  bomb  made  of  this  metal  has  been  in  service  for  a 
number  of  years  and  has  been  used  in  upwards  of  2,000  calorimetric  determina- 
tions without  giving  any  evidence  of  corrosion.  Many  of  the  determinations 
were  made  parallel  with  a  platinum-lined  instrument,  and  throughout  the  series 
there  was  every  evidence  of  an  exact  equivalent  in  the  behavior  of  the  alloy 
(Illium)  bomb. 

The  calorimeter  complete  with  bomb,  water  container,  insulating  vessel  with 
cover,  stirrer  and  pulley,  oxygen  connection  with  gauge,  needle  valve  and 
couplings,  octagon  holder  for  bomb,  with  spanner  wrench,  one-half  dozen  cap- 
sules of  special  alloy,  reading  lens  and  support,  special  ignition  wire  and  gaskets.

2183     CALORIMETER— Parr's   Adiabatic   with   "Illium"   bomb. 

Another  form  of  Calorimeter,  and  that  of  the  Adiabatic  type,  has  just  been  per- 
fected, and  its  operation  in  actual  use  has  been  so  eminently  satisfactory  that  it  is  now 
being  regularly  manufactured  for  the  trade.  It  is  the  completion  of  a  design  which  has 
been  in  process  of  development  for  some  years  by  Professor  S.  W.  Parr  of  the  Univer- 
sity of  Illinois. 

The  adiabatic  principle  has  been 
secured,  not  by  the  use  of  the  Dewar, 
or  vacuum  arrangement,  with  its 
somewhat  questionable  immunity 
from  variation,  nor  is  use  made  of 
any  chemical  or  electrical  method  of 
heating  the  surrounding  water.  The 
principles  involved  are  carried  out  as 
follows: 


A  supply  of  hot  and  cold  water  is 
automatically  provided  immediately 
underneath  the  desk  on  which  the 
calorimeter  is  installed.  This  may  be 
drawn  upon  either  to  raise  or  lower 
the  temperature  of  the  water  in  the 
surrounding  medium.  By  means  of  a 
stop  cock  and  overflow,  hot  water, 
for  example,  can  be  instantly  dis- 
charged into  the  jacketing  water.  The 
lag,  therefore,  is  only  that  incident 
to  the  stirring  of  the  water  and  the 
response  as  shown  on  the  thermom- 
eter occurs  at  once.

2185     CALORIMETER,  Emerson's,  one  of  the  most  modern  bomb  calorimeters  for 
determining  the  heating  value  of  solid  and  liquid  fuels. 

The  Bomb  is  made  of  steel,  consisting  of  two  cups  joined  by 
means  of  a  heavy  steel  nut.  The  lining  is  of  sheet  metal,  spun  to  fit 
the  interior.  The  pan  holding  the  combustible  is  usually  of  nickel 
and  so  are  the  supporting  wires.  The  fuse  wire  for  general  fuel 
testing  should  be  of  platinum. 

The  Calorimeter  jacket  is  a  double  walled  copper  tank.  The 
calorimeter  bucket  is  of  light  sheet  brass. 

The  Stirring  Device  consists  of  a  propeller  fitted  shaft  inclosed 
in  a  vertical  tube  to  facilitate  its  action  in  circulating  the  water.  The 
stirrer  is  mounted  on  a  post  on  the  calorimeter  jacket  as  is  the 
thermometer  holder.  The  motor  is  driven  by  a  110-volt  circuit  and 
should  be  placed  in  series  with  a  16  C.  P.  lamp.  If  so  desired,  a 
battery  driven  motor  can  be  specified  in  ordering  the  apparatus. 

The  Oxygen  Piping  is  especially  strong  and  durable  and  is 
designed  for  two  cylinders.  Other  accessories  such  as  iron  plate 
holder,  swivel  table,  spanner  or  wrench  are  furnished  with  the  outfit.

2191     CALORIMETER,  The  Riche  Adiabatic. 

The  Riche  Adiabatic  Calorimeter  is  constructed  along  practical  lines,  capable  of 
standing  the  strain  of  continuous  work.  The  inside  walls  of  the  cabinet  are  lined 
with  one  inch  pressed  cork  and  on  the  cover  in  addition  to  the  cork  is  a  piece  of  half- 
inch  hairfelt,  making  a  tight  joint  with  the  top  of  the  vacuum  cup.  All  fittings  are 
brass,  heavily  nickeled. 

The  rapidity  with  which  results  are  obtained  is  a  decided  advantage.  A  complete 
determination  may  be  made  in  10  to  15  minutes  with  an  accuracy  of  (1)  three  calories, 
thus  saving  from  fifty  to  seventy-five  per  cent  of  time.  The  maximum  time  required 
for  reading  is  eight  minutes. 

The  bomb  is  of  the  Mahler-Kroeker  two  valve  porcelain  lined  type,  guaranteed  for 
3,000  determinations,  but  it  should  be  good  for  at  least  8,000  combustions  if  proper 
cafe  is  taken.

2193  CALORIMETER — Sargent's,  for  gas:  The  only  apparatus  conforming  with  the 
suggestions  of  American  authorities,  being  the  most  advanced  type  of  instru- 
ment for  testing  the  thermal  value  of  inflammable  gases.  It  has  the  following 
advantages: 

(1)  The  discharge  water  is  weighed  to  one-hundredth  of  a  pound  instead 
of  being  measured  in  a  graduate.  (2)  The  discharge  water  is  switched  auto- 
matically from  one  receptacle  to  another  after  each  one-tenth  of  a  cubic  foot 
of  gas  is  burned.  This  eliminates  errors  due  to  hand  manipulation.  (3)  Inlet 
and  outlet  thermometers  are  on  the  same  level  so  that  they  can  be  read  almost 
simultaneously.  (4)  A  Wet  Pressure  Governor  controls  the  pressure  of  the 
gas  entering  the  burner  and  a  constant  pressure  is  easily  maintained  by  means 
of  adjustable  weights.  (5)  To  maintain  a  constant  flow  the  inlet  and  outlet 
pipes  are  provided  with  wiers.  A  graduated  quadrant  valve  regulates  the 
amount  of  water  used.  (6)  Since  a  determination  can  be  made  every  three  or 
four  minutes,  a  curve  of  the  heat  value  extending  over  any  length  of  time  may 
be  plotted.  (7)  The  heat  value  of  the  gas  is  determined  directly  in  B.  T.  U. 
(8)  The  Bunsen  burner  has  two  tips  and  is  adjustable  for  gas  having  100  to 
1500  B.  T.  U.  per  cubic  foot.  (9)  The  calorimeter  is  made  of  copper  and  brass 
and  is  handsomely  nickel-plated.  (10)  The  Wet  Test  Gas  Meter  is  made  of 
heavy  brass  and  tin  and  has  a  water  level  indicator  outside  of  the  gauge  glass. 
The  meter  is  graduated  to  0.001  cubic  foot.

CALORIMETER— Parr's,  for  Gas,  devised  by 
Prof.  S.  W.  Parr,  of  the  University  of  Illinois. 
This  instrument  is  constructed  upon  radically 
new  lines.  A  standard  and  an  unknown  gas 
are  burned  side  by  side  under  identical  con- 
ditions. A  ratio  of  values  is  thus  established 
in  a  manner  which  eliminates  errors  due  to 
radiation,  metering,  variable  pressures,  speed 
of  combustion,  etc.,  etc.  This  is  decidedly  the 
most  accurate  apparatus  thus  far  devised  for 
the  measuring  of  heat  values  of  gases  of  all 
types.  Price $275.00

2198  CARBONATE  APPARATUS— Barker.  For  determining  the  percent- 
age of  carbonates  in  limestone  and  other  materials. 

The  principle  upon  which  the  apparatus  is  based  is  that  of  a 
hydrometer  which  takes  account  of  the  law  that  when  an  object  (the 
hydrometer)  is  immersed  in  a  liquid,  it  is  buoyed  up  by  a  force  equal 
to  the  weight  of  the  liquid  displaced  by  the  object.  In  this  apparatus 
the  carbon  dioxide  gas  released  by  the  sample  decreases  the  weight. 
The  apparatus  consequently  rises  in  the  water  in  which  it  is  immersed, 
recording  on  the  graduated  scale  the  percentage  of  carbonates  from 
which  gas  escaped. 

Every  hydrometer  is  thoroughly  tested  before  leaving  the  factory 
and  is  accompanied  by  a  certificate.

2229 


2229 -CEMENT  TESTING  MACHINE,  Olsen's  New  Automatic  Shot  Form.     The 

principal  advantages  of  this  machine  are  as  follows: 

The  machine  is  automatic  to  its  full  capacity  and  is  not  touched  from 
start  to  finish  of  test.  The  instant  the  briquette  breaks,  the  breaking  lead  is 
read  on  the  dial  of  the  scale. 

The  load  is  applied  with  absolute  smoothness,  and  impact  from  falling 
shot  is  eliminated. 

The  cut-off  on  the  shot  kettle  is  practically  instantaneous.  All  shot  that 
has  escaped  from  the  kettle  has  already  done  its  work  and  the  column  of 
falling  shot  in  the  air  when  the  specimen  breaks  is  therefore  weighed  as  it 
should  be. 

A  new  grip  which  brings  the  strain  uniformly  on  the  specimen  is  used. 

The  briquette  hangs  clear  of  the  frame  of  the  machine,  giving  plenty  of 
room  for  the  hands  when  adjusting  specimens. 

This  is  widely  used  and   thoroughly  satisfactory  outfit;  1,000  Ibs.  capacity;  length,

2249    CENTRIFUGE,  Purdy  Electric,  with  Adjustable  Speed  Regulator. 

In  order  to  regulate  the  speed  of  the  Centrifuge  more  delicately  than  is  possible 
with  the  regular  device  attached  to  the  instrument  and  to  obtain  any  rate  of  speed 
desired  within  the  scope  of  the  motor  or  to  keep  the  instrument  at  a  fixed  speed  where 
the  current  varies  or  the  load  is  increased,  a  speed  regulator  is  necessary.  It  is  often 
important  that  an  entire  series  of  experiments  should  be  carried  on  with  an  absolutely 
uniform  speed.  This  is  mostly  not  possible  without  a  speed  regulator,  owing  to  the 
varying  strength  of  all  electric  currents.  Again,  extremely  fragile  sediment  must  often 
be  handled  with  medium  speed,  while  very  light  sediments  require  the  highest  speed  to 
produce  sedimentation. 


The  speed  regulators  can  be  supplied  with  any  of  the  Purdy  Centrifuges,  Nos. 
2238-2243  inclusive,  for  either  the  direct  or  alternating  60  cycle  current  of  100  to  115

inclusive,  at  an  additional  cost  of  $14.50

2347    COLORIMETER,  Kennicott-Sargent.     It   is   especially   recommended   on 

account  of  the  rapidity  of  operation  while  maintain- 
ing the  highest  standard  of  efficiency  possible  with 
the  color  method.  The  standard  and  unknown  solu- 
tions come  in  contact  with  glass  only.  The  apparatus 
consists  of  a  wooden  camera  which  exhibits  on  a  dark 
background  the  pictures  of  the  sample  and  the  stand- 
ard side  by  side  in  the  form  of  two  large  round  discs 
of  color  by  means  of  light  transmitted  through  the 
sample  and  standard  by  means  of  swinging  mirrors. 
The  body  of  the  camera  is  of  the  correct  shape  and 
focal  length,  enabling  the  observer  to  place  his  face 
close  to  the  mouth  of  the  instrument  whereby  all  side 
lights  and  distracting  rays  are  eliminated.  The  glass 
parts  consist  of  a  tubular  reservoir  provided  with  a 
glass  plunger.  From  the  bottom  of  a  graduated  glass 
chamber  there  extends  a  glass  tube  connected  with 
the  bottom  of  the  reservoir,  also  a  corresponding 
tube  for  the  unknown  solution  to  be  tested.

2347a    COLORIMETER,  Kennicott-Sargent's,  modified  by  Campbell- Hurley.  In 

this  colorimeter  the  method  of  comparing  the  colors 
is  similar  to  that  used  in  a  half  shade  polariscppe, 
the  field  consisting  of  a  circular  disc  of  light  divided 
vertically  into  two  parts.  The  comparison  tubes  are 
those  of  the  well-known  Kennicott-Sargent  instru- 
ment in  which  the  unknown  is  placed  in  the  left  hand 
tube  while  the  color  is  matched  by  raising  or  lower- 
ing the  level  of  a  standard  solution  in  the  right  hand 
tube  by  means  of  a  glass  plunger  working  in  the 
attached  reservoir. 

A  person  looking  through  the  eye  piece  observes  a 
single  field  divided  vertically  by  an  almost  im- 
perceptible line  representing  the  contact  point  of  the 
hemispheres  of  the  two  comparison  tubes.

HESS-IVES  TINT  PHOTOMETER 


2347b 


2347e 


The  Ives'  Tint  Photometer  is  an  instrument  for  comparing  different  shades  and 
hues  of  light  colored  materials  or  liquids  with  each  other  and  with  fixed  standards,  in 
order  to  differentiate  and  classify  them,  and  give  them  numerical  expression.  It  is 
adapted  particularly,  and  far  better  than  any  other  existing  means  or  device,  to  tests 
of  paper-pulps,  different  hues  and  grades  of  white  and  tinted  paper,  transparency  of 
waxed  and  similar  papers,  color  of  oils  and  other  liquids,  qualities  of  flour  as  shown 
in  prepared  baked  samples,  white  pigments  in  oil  or  turpentine,  cottonseed  meal, 
etc.,  etc. 

The  Ives'  Tint  Photometer  is  used  like  a  telescope,  presenting  to  the  eye  a 
circular  field  with  vertical  hairline  central  division,  one  side  of  which  is  filled  through 
a  slit  with  light  directly  from  a  standard  white  magnesia  block,  while  the  other  is 
filled  through  another  slit  with  light  from  the  sample  to  be  compared,  measured  and 
given  numerical  expression.  The  slits  are  adjustable,  with  a  reading-scale,  and  the 
light  coming  through  them  is  spread  evenly  across  the  respective  half  fields  by  means 
of  a  patent  revolving  optical  mixing-wheel  between  the  slits  and  the  field  lens. 
Especial  attention  is  called  to  the  fact  that  personal  color  equation  and  even  a  marked 
degree  of  color  blindness  do  not  affect  the  readings  obtained  with  the  Tint  Photometer. 

In  order  to  assure  definite  and  constant  illumination  of  standard  and  sample  a 
"daylight"  lamp  must  be  employed. 

For  other  special  purposes,  such  as  measuring  the  transparency  of  waxed  and 
similar  papers  and  substances,  or  light  colored  liquids  in  long  tubes,  special  fronts 
are  provided,  at  an  additional  cost  of  from  $5  up.

placing  a  4-oz.  bottle  of  oil  under 
examination  in  one  of  the  circular 
compartments  of  the  instrument.  In 
he  opposite  compartment  place  a 
l-oz.  bottle  of  Water  White  Gaso- 
line or  Distilled  Water.  Then  place 
one  of  the  standard  glasses  in  the 
slot,  and  close  the  slide.  The  instru- 
ment should  be  taken  to  a  window, 
where  the  observer,  looking  through, 
can  compare  the  color  of  the  oil 
with  the  standard  glass. 

Filtered  Cylinder  Oils.  To  determine  the  color  of  Filtered  Cylinder  Oils  they  must  first  be  mixed 
with  Water  White  Gasoline  in  the  proportions  of  15%  Oil  and  85%  Gasoline.  Then  proceed  as  described 
for  determining  color  of  Neutral  Oils.

2465a  CRUCIBLE  HOLDER,  Sargent's,  for  filtering  crucibles.  The 
simplest  apparatus  for  the  purpose  on  the  mar- 
ket. It  is  of  special  value  where  the  unob- 
structed use  of  the  entire  sides  and  bottoms  of 
porous  filters  is  desired,  as  it  grasps  only  about 
one-eighth  of  an  inch  of  the  upper  rim  of  the 
crucible.  Can  be  instantly  installed  or  removed 
for  cleaning.  Will  fit  any  ordinary  sixty  degree 
funnel.  Can  be  used  with  any  crucible  on  the  2465c 

market,  such  as  Gooch,  Caldwell  or  porous 
Alundum  styles.  Made  of  one  piece  of  soft  rub-

CRUSHERS 


Ready  for  use.  Opened  for  cleaning. 

2466 

NO.  1  OR  SMALL  CASE  CRUSHER,  HAND  AND  POWER 

2466  CRUSHER,  Case.  The  Case  Improved  Laboratory  Crusher  is  designed  to  meet 
the  constantly  increasing  demand  for  a  strong  Laboratory  Ore 
Crusher  with  greater  capacity  than  any  other  similar  Crusher.  We 
unhesitatingly  recommend  it  as  being  the  strongest,  fastest  and  best 
Laboratory  Crusher  ever  built. 

The  above  cuts  represent  in  detail  the  Combination  Hand  and  Power  Machine, 
which  has  the  essential  features  of  strength  and  speed,  and,  at  the  same  time,  requires 
the  least  power  of  any  Crusher,  for  work  accomplished,  on  the  market. 

This  Crusher  is  the  most  easily  cleaned  Crusher  manufactured.  It  can  be  so  thor- 
oughly cleaned  that  there  is  no  possibility  of  salting.  The  simple  turning  of  a  large 
hand  nut  loosens  the  stationary  jaw,  which  may  be  removed  and  brushed  off.  This 
large  hand  nut  serves  a  double  purpose  —  it  is  sufficiently  large  so  that  it  gives  great 
leverage  and  the  jaw  does  not  work  loose  when  the  Crusher  is  in  motion.  The  movable 
jaw  is  provided  with  loop  handle  cast  on  top,  by  which  the  jaw  is  lifted  out  of  the 
socket  for  cleaning. 

Another  special  feature  with  reference  to  the  jaws  is  that  both  are  pivoted  from  a 
center,  so  that  when  one  end  becomes  worn  it  may  be  reversed  and  you  receive  double 
wear  from  the  Crusher  plates. 

The  Case  Crusher  is  shipped  with  three  replaceable  shims  or  liners  which  fit  be- 
tween the  stationary  jaw  and  the  Crusher  frame.  By  inserting  these  shims,  your  prod- 
uct may  be  ground  to  any  fineness. 

This  machine  is  lubricated  by  means  of  grease  cups  in  place  of  the  old  method  of 
using  oil,  which  means  that  it  will  run  for  days  with  very  little  attention. 

The  capacity  of  the  Crusher  of  this  character  depends  on  the  nature  of  the  product 
to  be  crushed.  This  machine  will  take  rock  or  soft  substances  2l/2"  in  diameter  re- 
ducing so  that  same  will  pass  through  a  10  mesh  sieve  or  finer  at  the  rate  of  from  50  to 
150  pounds  per  hour. 

The  shaft  is  1^2"  in  diameter,  driven  by  a  9"  pulley  with  a  2^4"  face,  at  from  450  to 
500  revolutions  per  minute,  and  requires  1  H.  P.  for  general  use.  Opening  of  jaws, 


All  parts  of  this  machine  are  made  on  jigs  in  exact  duplicate,  consequently  replace- 
ments can  be  had  at  minimum  expense.  In  other  words,  the  Case  Crusher  is  a  thor- 
oughly standardized  machine. 

Floor  or  bench  space  required  for  small  size:  14j4"x21".  Net  weight:  140  Ibs. 
Shipping  weight:  165  Ibs. 

Kindly  compare  all  of  the  above  good  Crusher  features  when  in  the  market  for  a 
Crusher  and  make  no  mistake.

LARGE   SIZE  LABORATORY   CRUSHER,  POWER   ONLY 

2467  CRUSHER,  Case,  large  size  for  power  only.  In  construction,  it  is  an  exact 
duplicate  of  the  smaller  Crusher,  having  all  the  essential  fea- 
tures, but  is  designed  for  greater  capacity  and  heavier  work — 
for  such  samples  as  are  required  by  large  mills  and  smelters. 
This  machine,  like  the  smaller,  is  easily  cleaned  by  removing 
the  stationary  jaw  and  lifting  the  movable  jaw  by  handle  cast 
at  the  top  for  this  purpose.  For  machine  of  this  size,  we 
recommend  a  2-horse  power  motor  and  a  speed  of  400  revolu- 
tions per  minute.  The  shaft  is  lli  inches,  driven  by  a  14 
inch  diameter  pulley  with  4  inch  face.  Loose  pulley  made 
slightly  smaller  so  as  to  take  strain  off  the  Crusher  bearing  and 
shafting  when  not  in  use.  The  Crusher  jaws  are  10^4x4^ 
inch  face.  Jaw  opening:  3J4x4j4  inch.  Floor  space:  27x28

2474  CRUSHERS,  Taylor's  Hand  Crusher,  a  low  priced  machine,  substantially 
made,  for  reducing  ore,  coal,  etc.,  to  a  fine  powder.  The  jaws 
are  3  inches  wide  and  open  at  the  top  1^4  inches.  Forty 
pounds  of  the  hardest  rock  may  be  crushed  in  one  hour,  20 
per  cent  of  this  will  pass  a  60-mesh  sieve.  By  tightening 
the  adjustment  and  crushing  again,  it  will  all  pass  a  60-mesh 
or  finer  sieve.  Weight,  100  pounds,  packed  for  shipment $18.00 


2475 


THE  CASE  IMPROVED  PULVERIZER 
Open  for  Cleaning 


2475    PULVERIZER,  Case. 


Capacity — The  capacity  of  the  Case  Grinder  depends  on 
the  hardness  of  the  ore  and  the  size  of  the  ore  fed 
through  the  Hopper  and  the  fineness  to  which  it  is 
ground.  In  actual  tests,  we  find  the  machine  capable 
of  grinding  8  ounces  of  quartz,  92%  of  which  passed 
through  an  80-mesh  sieve,  in  10  seconds;  5  pounds 
sulphide  ore  in  zy2  minutes,  84%  of  which  passed 
through  a  120-mesh  sieve. 

Adjustment — Ore  may  be  ground  to  any  degree  of  fine- 
ness desired,  from  60  to  150  mesh  by  a  very  simple  ad- 
justment, consisting  of  a  hand  screw,  which  is  fastened 
to  the  rear  bearing  and  acts  on  the  shaft,  controlling 
the  distance  between  the  stationary  and  revolving  disc. 

We  recommend  a  speed  of  1,000  r.  p.  m.,  which  requires 
about  3  h.  p.

EVAPORATORS 

Waste  products  become  by-products  when  properly  handled.  During  the  last  quar- 
ter of  a  century  the  Swenson  Evaporator  Company  has  been  instrumental  in  the  de- 
velopment of  a  large  variety  of  by-product  industries.  Such  interesting  instances  as  the 
recovery  and  marketing  of  products  from  packing  house  waste  waters,  iron  sulphate 
from  wire  and  plate  mills,  pickle  solutions,  etc.,  are  examples  of  successes  in  which 
they  properly  take  a  large  share  of  credit. 

The  Swenson  Evaporator  Company  have  installations   at  several  institutions   of 
learning  throughout  the  country,  among  which  the  University  of  Michigan,  Massachu- 
setts Institute  of  Technology,  and  Armour  Institute  of  Technology  are  the  most  noted 
examples. 
Your  further  attention  is  directed  to  the  Swenson  advertisement  in  the  advertising:  section.

VACUUM  OVEN 

2645/1  "The  Standard  F.  A.  C.  Vacuum  Oven  has  been  designed  with  the  idea  of 
affording  a  simple  and  compact  vacuum  oven  which  will  give  as  uniform  tem- 
peratures as  possible  on  the  shelf.  It  consists  of  an  iron  casting  of  rectangular 
sections  with  hinged  front  door,  which  is  accurately  counterpoised.  The  door 
is  made  tight  by  a  gasket  and  which  can  be  lowered  on  opening  the  oven  so 
as  to  form  a  shelf  on  which  samples  may  be  rested.  The  oven  contains  but 
one  shelf  which  is  heated  from  above  as  well  as  below  by  means  of  resistance 
coils.  Several  thermometer  holes  are  provided  in  order  to  ascertain  definitely 
the  temperature  at  different  points  on  the  shelf.  '  The  entire  oven  is  supported 
by  means  of  a  4"  standard  pipe  which  screws  into  the  base  of  the  oven  and 
which  in  turn  is  supported  by  being  screwed  into  a  blind  flange  of  suitable 
diameter  which  rests  on  the  floor  or  work  table."

8711  FILTER  PAPER,  Whatman  No.  40  (S.  &  S.  No.  5892,  White  Ribbon),  a  double- 
acid-washed  paper  of  very  low  ash,  all  mineral  matter  having 
been  removed  by  treatment  with  hydrochloric  and  hydro- 
fluoric acids.  Filters  rapidly  and  retains  fine  precipitates. 
This  is  the  standard  double-washed  grade  for  analytical  pur- 
poses. Excellently  suited  for  Barium  Sulphate  when  prop- 
erly precipitated  and  filtered  hot,  also  for  Lead  Sulphate,  and 
for  crystalline  precipitates,  such  as  Magnesium-Ammonium 
Sulphate,  etc.

2712  FILTER  PAPER,  Whatman  No.  41  (S.  &  S.  No.  589,  Black  ribbon),  a  double- 
acid-washed  paper  similar  to  No.  40,  but  more  open  in  texture 
and  therefore  filters  more  rapidly.  Suitable  for  Iron,  Alumi- 
num, and  other  gelatinous  precipitates  which  can  be  filtered 
quickly  and  washed  rapidly  and  easily.  Widely  used  in  deter- 
mining Silicon  in  Iron  and  Steel  Analysis.

2713  FILTER  PAPER,  Whatman  No.  42  (S.  &  S.  No.  589s,  Blue  Ribbon),  a  double- 

acid-washed  paper,  similar  to  No.  40,  but  much  harder  and 
extremely  close  in  texture.  On  account  of  its  close  texture 
it  is  recommended  for  use  with  the  filter  pump  and  as  folded 
niters  where  possible.  Especially  adapted  for  the  finest  pre- 
cipitates which  tend  to  pass  through  the  filter  paper,  such  as 
Barium  Sulphate  when  precipitated  in  cold  solution,  and  in 
general  for  precise  analytical  work  where  speed  is  not  im- 
portant.

acid-washed  paper,  of  the  same  stock  as  No.  40,  but  having 
been  subjected  to  an  additional  chemical  process  which  renders 
it  fat-free.  Especially  suited  for  the  recovery  of  the  ether 
extract  in  the  Roese-Gottlieb  Fat  Test,  and  in  general  for 
any  purposes  requiring  a  fat-free  paper.

paper  of  thinner  substance  and  lower  ash  content  than  the 
preceding  numbers.  It  will  retain  the  finest  precipitates,  but 
is  slightly  slower  in  filtration  than  No.  40.  No.  44  is  recom- 
mended for  use  when  the  greatest  possible  degree  of  accuracy 
in  quantitative  work  is  required.

2715a  FILTER  PAPER,  Whatman  No.  50  (S.  &  S.  No.  575),  a  paper  specially  hard- 
ened by  treatment  with  Nitric  Acid.  Very  tough,  will 
resist  great  pressure,  and  retain  the  very  finest  precipitates. 
Can  be  used  repeatedly,  the  hard  smooth  surface  permitting 
precipitates  to  be  scraped  or  washed  off  without  injury  to 
the  paper.  Especially  recommended  for  use  with  vacuum. 
Suitable  for  very  fine  precipitates  and  for  filtering  corrosive 
liquids  such  as  Acids  and  strong  Alkalies.  Should  be  used 
when  it  is  desired  to  transfer  a  precipitate  without  ignition. 
Widely  used  for  filtering  Biological  products,  as  the  hardened 
surface  prevents  contamination  of  the  filtered  product  by 
particles  of  paper  when  scraped  off.  Can  be  used  as  a  sub- 
stitute for  platinum  cones,  and  as  supports  for  large  folded 
.  filters  to  prevent  them  bursting  at  the  points.

FURNACES— HOSKINS'  ELECTRIC 

TYPE  FD 

These  furnaces,  Type  FD,  are  designed  for  industrial  and  laboratory  purposes. 
Their  construction  eliminates  all  the  shortcomings  commonly  found  in  wire-wound 
electric  furnaces.  Attention  is  particularly  called  to  the  fact  that  all  parts  of  this 
furnace  which  require  renewals  are  very  easily  accessible  and  can  be  replaced  by  the 
operator  himself.  No  part  of  this  furnace  need  be  returned  to  the  factory  when  in  need 
of  repairs. 

The  heating  unit  is  surrounded  by  bonded  kieselguhr,  backed  up  with  asbestos  and 
magnesia  slabs.  It  is  believed  that  this  insulation  is  the  most  efficient  that  is  available 
and  it  is  responsible  for  the  low  power  consumption  of  this  FD  line. 

The  door  of  the  furnace  is  of  the  sliding  type  and  has  an  adjustable  counterbalance, 
which  causes  the  door  to  remain  open  at  any  desired  point  or  close  automatically. 

Construction — The  heating  element  in  these  furnaces  is  of  heavy  Chromel  "A" 
wire,  wound  in  spiral  coils.  The  refractory,  around  which  this  wire  is  wound,  has 
spirally  built  ribs  on  its  surface,  which  give  the  walls  of  the  heating-chamber  a  greater 
strength,  and  at  the  same  time  the  spaces  between  these  ribs  act  as  grooves  in  which 
the  wire  is  wound  and  is  thus  automatically  and  properly  spaced. 

Temperature — The  maximum  safe  operating  temperature  of  the  FD  Furnace  is 
1830°  F.  (1000°  C).  The  minimum  temperature  that  can  be  maintained  with  the 
standard  rheostat  is  about  900°  F.  (480°  C.).  With  special  rheostats,  they  can  of  course 
be  operated  at  lower  temperatures,  with  the  exception  of  the  Tube  Furnace. 

Operation — Hoskins  Furnaces,  Type  FD,  are  built  for  110  or  220  volt  circuits,  alter- 
nating and  direct  current.  Special  windings  will  be  made  for  any  voltage  between  100 
and  300.  All  styles  require  the  use  of  a  rheostat,  which  is  the  only  auxiliary  apparatus 
required.

ing and  annealing  of  small  metal  parts.)  Included  with  each  furnace  is  a 
six-foot  twin  connector  cord  with  attachments. 

Larger  Sizes — The  sizes  designated  by  FD-206  and  207  are  equipped  with 
an  iron  stand,  which  puts  the  furnace  shelf  about  40  inches  above  the  floor. 
The  FD-206  and  207  are  wound  with  three  parallel  circuits,  the  rheostat 
being  in  one  of  them.  The  three  circuits  allow  very  close  temperature  con- 
trol, any  temperature  between  that  of  the  room  and  1000°  C.  being  easily 
maintained.

TYPE  FB— FURNACES 

110-220-440  VOLTS 

Hoskins  Type  FB  Electric  Furnaces  are  for  work  requiring  temperatures  up  to 
1100°  C.  (2000°  F.).  They  are  especially  adapted  to  heavy  duty  or  continuous  operation, 
and  are  capable  of  twenty-four-hour-per-day  service  if  required.  The  heating  units  of 
all  Type  FB  Furnaces  can  be  removed  and  replaced  by  the  operator  within  a  few 
minutes. 

Temperature — The  maximum  working  temperature  of  all  Type  FB  Furnaces  is 
1100°  C.  (2000°  F.).  The  minimum  temperature  at  which  the  rheostat-controlled  fur- 
naces can  be  maintained  (after  having  come  up  to  heat)  varies  between  316°  C.  (600°  F.) 
and  536°  C.  (1000°  F.)  for  the  different  designs.  The  Types  FB  204  to  235  inclusive  can 
be  maintained  at  any  temperature  between  that  of  the  room,  in  which  the  furnace  is 
operating,  and  1100°  C.  (2000°  F.). 

Operation — Type  FB  Furnaces  operate  on  low  voltages  (10  to  67.5  volts),  for 
which  reason  they  are  best  adapted  for  use  on  alternating  current  circuits  in  connection 
with  a  transformer.  They  are  regularly  supplied  for  use  on  110,  220  or  440  volt,  25  or  60 
cycle  lines,  but  can  be  supplied  for  other  voltages  and  cycles  at  prices  which  will  be 
quoted  on  application.  Temperature  regulation  of  the  Types  FB  204  to  235,  inclusive, 
is  by  means  of  regulating  transformers;  the  types  of  smaller  power  in-put  are  con- 
trolled by  means  of  rheostats. 

Power  Consumption — None  of  the  furnaces  described  in  this  bulletin,  of  course, 
draws  the  full  load  except  when  heating  up.  Once  up  to  heat,  they  operate  on  a  greatly 
reduced  current,  in  some  cases  less  than  half  the  maximum.

2916(j)  FURNACE,  Multiple  Tube  Combustion  Furnace  (Type  FB-235).  This  furnace 
is  of  great  convenience  and  economy  where  a  large  number  of  carbon 
determinations  are  to  be  made,  using  the  direct  combustion  method.  Five 
carbon  combustions  can  be  run  simultaneously,  and  in  approximate  terms, 
at  one-fifth  the  attention,  one-third  less  space  and  correspondingly  lower 
up-keep  cost  than  that  represented  by  five  single  tube  furnaces  of  the 
same  capacity. 

The  combustion  tubes  are  heated  by  direct  radiation  from  the  "hair- 
pin" heating  units,  between  which  the  tubes  lie.  Temperature  regulation  is 
accomplished  by  means  of  a  regulating  transformer.  This  furnace  is  also 
made  in  the  FD  type.  See  No.  2916(e).

2916 (k)  FURNACE  CORES,  Alundum.  For  the  construction  of  small  wire  resistance 
electric  furnaces  Alundum  refractory  cores  meet  the  criteria  of  the  most 
efficient  material  for  this  purpose.  The  resistor  should  be  spiralled  and 
wound  and  then  embedded  in  Alundum  cement.  Thus,  fully  protected,  the 
wire  does  not  corrode  under  the  most  severe  conditions,  since  the  Alundum 
mixtures  are  chemically  inert.  In  addition  to  this  the  core  has  high  heat 
conductivity  and  does  not  become  an  electrical  conductor  even  at  the 
highest  temperatures  obtained  in  the  furnace.* 

Those  listed  below  we  aim  to  carry  constantly  in  stock.    Special  sizes 
and  styles  made  to  order.

FURNACE  CEMENT— HYTEMPITE 


Hytempite  is  a  high  temperature  fire  brick  cement  which  has  proven  of  great  value 
in  the  laying  of  firebrick  and  in  the  general  repair  of  all  types  of  furnaces,  retorts, 
ladles  and  so  forth.  It  is  a  scientifically  compounded  refractory  plastic  material  and 
forms  a  lasting  union  between  the  materials  to  be  joined,  retaining  its  strength  regard- 
less of  the  heat  to  about  3100°  F.  It  is  better  than  fire  clay  because  fire  clay  and  water 
has  no  binding  strength.  It  does  not  loosen  with  expansion  or  contraction.  Hytempite 
withstands  the  cutting  action  of  the  flames  and  is  especially  recommended  for  oil 
furnaces.  It  is  largely  used,  also,  as  a  coating  or  wash  or  to  smoothen  and  harden  the 
surface  of  a  lining  to  protect  it  from  abrasion. 

In  25,  50,  100  and  225  pound  kegs  and  in  barrels  of  800  pounds.  Also  furnished 
in  ton  lots  with  prices  on  application. 

Below  is  illustrated  a  typical  test  of  a  firebrick  broken,  repaired  with  HYTEMPITE 
and  then  re-broken.  Note  the  last  illustration,  showing  location  of  new  fracture. 


The  Break  (see  note) 


The  Test  (see  note) 


NOTE.— The  brick  illustrated  was  broken  and  repaired  with  HYTEMPITE,  sub- 
jected to  a  high  temperature,  and  upon  being  tested  fractured  as  shown,  proving  the 
repair  stronger  than  the  brick  structure. 

Prices  on  application. 


2916(e)  FURNACE  CEMENT.  Alundum  cement  is  recommended  for  use  in  con- 
nection with  Alundum  muffles,  cores,  and  wherever  a  refractory  cement 
with  high  thermal  conductivity  is  desirable.  It  has  the  same  general 
proprieties  as  the  refractory  article  and  is  furnished  in  the  form  of  a 
dry  powder,  which,  when  mixed  with  sufficient  water  to  make  a  thick 
paste,  is  ready  for  application.  The  material  should  be  allowed  to  dry 
and  finally  heated  to  a  good  red  heat.  In  burning,  the  heat  should  be 
raised  as  high  as  possible,  as  this  will  give  the  cement  a  body  similar 
in  character  to  the  refractory  article.

LABORATORY  FURNITURE 

The  laboratory  is  becoming  more  and  more  a  factor  in  education,  in  the  profession, 
and  in  the  trades.  We  furnish  laboratory  furniture  not  only  for  educational  institutions, 
but  for  private  experimental  and  clinical  laboratories,  such  as  meet  the  needs  of 
physicians,  commercial  chemists  and  pathologists.  We  use  the  best  grade  of  lumber 
in  the  manufacture  of  our  furniture.  It  is  kiln  dried  by  the  most  modern  process  known. 


We  furnish  all  the  plumbing  complete  to  the  floor  line  ready  to  be  screwed 
together  and  connected  Plans  showing  the  exact  location  of  the  different  outlets 
should  be -obtained  before  the  floor  pipes  are  laid.  All  sinks  and  gutters  furnished  in 
connection  with  our  laboratory  furniture  are  made  from  lJ4-inch  soapstone.  This  stone 
has  no  equal.  It  will  withstand  the  action  of  acid  better  than  any  other  known  sub- 
stance. 


While  it  is  impossible  to  list  all  types  of  Laboratory  Furniture 
we  list  at  least  representative  ones  of  Laboratory  Tables  for  Students' 
and  Professors'. use  for  Bacteriological  and  Industrial  purposes  and

determinations  of  any  or  all  of  the  following  constituents,  carbon  dioxide, 
illuminants,  oxygen,  carbon-monoxide,  methane,  hydrogen  and  nitrogen, 
can  be  made  in  from  twenty  to  twenty-five  minutes.  The  saving  in  time 
is  effected  by  the  elimination  of  the  necessity  of  shifting  the  gas  from 
one  portion  of  the  apparatus  to  another.  With  each  outfit  we  send  a

2963-1  GENERATOR— Parson's  Automatic,  for  H2S,  CO2  and  H.  This  is  the  most 
popular  generator  for  large  requirements;  used  by  the  majority  of  edu- 
cational laboratories  throughout  the  country  to  distribute  HzS  to  labora- 
tory classes. 

The  apparatus  is  perfectly  automatic  in  action,  and  the  refuse  is  auto- 
matically removed,  while  the  pressure  is  almost  constant.  Only  fresh  acid 
comes  in  contact  with  the  solid  reagent,  so  that  the  full  strength  of  the 
acid  is  utilized.  There  are  no  stoppers  or  valves,  the  apparatus  being  con- 
trolled entirely  from  the  exits.  It  requires  practically  no  attention,  is 
easily  cleaned  and  refilled  without  being  taken  apart.  Forty  outlets  flow- 
ing at  the  rate  of  two  bubbles  every  second  can  be  furnished  by  one 
apparatus.  Most  instructors  prefer  exits  for  use  with  hydrogen  sulphide 
to  be  situated  in  the  hoods;  the  rubber  connection  containing  a  small 
piece  of  capillary  tubing,  being  concealed  behind  a  block,  screwed  to  the 
wall;  thus  the  student  sees  only  a  rubber  tube  protruding  from  a  hole,  and 
being  unaware  that  his  supply  is  limited  by  the  size  of  the  capillary,  has 
no  means  of  increasing  the  supply.  Waste  is  thereby  avoided.

2973  Gas  Regulator,  Roux,  Bi-metallic,  designed  to  meet  the  demands  for  an  accurate 
regulator  without  the  use  of  mercury  or  glass  in  its  construction.  It  is 
particularly  well  adapted  for  Incubators  and  other  Ovens  where  a  constant, 
even  temperature  is  desired.  Inlet  tube  E  is  connected  by  means  of  rubber 
tubing  to  the  gas  supply;  the  outlet  D  is  connected  in  the  same  manner 
with  the  burner  under  the  incubator.  A  is  a  set  screw  to  regulate  the  flow 
of  gas,  and  B  a  lock  nut;  C  is  a  small  set  screw  for  pilot  light.  Diameter 
of  tube,  1  inch.

2973 (b)  Gas  Regulator,  Greenman's,  made  entirely 
of  steel.  The  gas  entering  at  "C"  must  pass 
the  valve  "H"  before  passing  to  the  burner 
through  "D",  excepting  that  a  small  quan- 
tity, determined  by  the  screw  valve  "J" 
passes  through  the  by-pass  "I"  to  main- 
tain the  pilot  flame.  The  mercury  in  the 
tube  "A"  when  expanded  raises  the  valve 
"H"  against  the  conical  valve  seat  "G"  and 
the  valve  is  prevented  from  falling  too  far 
by  the  pin  at  "O."  The  volume  of  the  mer- 
cury is  controlled  by  the  rod  "K,"  which 
is  held  in  place  by  the  screw  "L."  By  ad- 
justing the  rod  "K"  and  the  screw  valve 
"J"  an  extremely  accurate  control  of  the 
gas  supply  and  the  temperature  may  be 
maintained.  The  slightest  increase  in  the 
volume  of  the  mercury  contained  in  the 
tube  "A"  produces  a  considerable  differ- 
ence in  the  height  of  the  mercury  in  the 
2973-3b  passage  "F"  and  the  float  "H,"  which  is 

about  two-thirds  submerged  in  the  mer- 
cury, is  carried  upward  and  closes  the  valve 
"G."  The  brass  tube  into  which  the  regu- 
lator is  to  be  inserted  should  be  filled  with 
glycerine  12.00

3060A    Attachment  for  BRINELL  Machine  to  read  the  depth  of  impression.   This 
attachment  permits  depth  readings  to  1/100  millimeters,  and  it  was 
constructed  when  it  was  found  that  the  depth  of  indentation  could  be 
more  accurately  measured  than  the  diameter  of  indentation.

3072  Instantaneous  Water  Heater,  giving  instantly  a  continuous  supply  of  water 
at  any  temperature,  from  boiling  to  lukewarm,  free  from  the  products 
of  combustion,  and  suitable  for  all  purposes.  Designed  to  hang  over 
lavatory  bowl  or  sink.  In  two  sizes;  large  size,  height  19  inches, 
projection  from  wall  8  inches;  small  size,  height  18  inches,  projec- 
tion from  wall  6  inches.  This  water  heater  is  more  especially  in- 
tended for  the  lavatory  and  the  general  odd  work  of  laboratory  and 
domestic  purposes  where  hot  water  is  constantly  wanted  quickly. 
The  gas  supply  should  be  from  a  5^-inch  pipe.  It  will  work  equally 
well,  but  at  a  proportionately  slower  rate,  with  any  gas  supply,  how- 
ever small.  The  speed  at  which  the  water  runs  rules  its  temperature. 
It  will  heat  1  pint  of  water  per  minute  from  50  to  130  degrees  Fahren- 
heit, or  will  boil  15  quarts  per  hour.  The  duty  of  the  larger  size  is 
about  double  that  above  given.  It  is  not  designed  for  baths.  Con- 
sumption of  gas:  large  size,  40;  small  size,  20  feet  per  hour. 

Note. — The  light  must  be  applied  to  the  gauze  before  the  gas  is 
turned. 

Recent  Improvements. — A  pilot  light  attachment,  which  auto- 
matically lights  the  burner  when  the  gas  is  turned  on;  also  a  coupled 
gas  and  water  tap,  operated  by  a  hand-wheel,  a  turn  of  which  lights 
the  burner  and  gives  an  immediate  flow  of  warm  water. 

3072b    Water  Heater,  small  size,  with  coupled  taps  and  pilot  light $38.00

3073  HEATER,  Instantaneous  Water  Heater,  height  9  inches.  This  gives,  when 
connected  with  a  water  tap,  hot  water  in  three  seconds  after  the  gas 
is  lighted,  either  boiling,  hot,  warm  or  cold,  the  water  being  pure  and 
fit  for  cooking  purposes.  In  one  minute  it  will  deliver  sufficient  hot 
water  for  washing  hands.  It  is  simple,  cheap,  not  liable  to  get  out 
of  order  or  wear  out.  Gas  supply  required,  ^-inch  clear  bore  pipe  and 
tap,  to  obtain  the  maximum  power,  at  which  it  consumes  about  60 
feet  per  hour.  It  will  work  at  a  proportionate  rate  with  any  gas  sup- 
ply, however  small.  If  frequently  used  for  long  periods  in  a  confined 
room,  the  products  of  combustion  should  be  carried  away.

3233 


3228  Hydroeik,  an  improved  form  of  the  Mason's  Hygrometer.  Consists  of  two 
thermometers  (wet  and  dry  bulb)  mounted  upon  the  outer  edge  of  a 
chart,  which  has  been  plotted  from  new  and  corrected  tables  pre- 
pared under  the  direction  of  the  United  States  Weather  Bureau. 

3232  The  Mason  Hygrometer,  while  invariably  recognized  as  the  most  accurate 

and  satisfactory  of  the  many  forms  of  hygrometers  in  use,  has  never 
enjoyed  the  popularity  which  its  merits  deserve,  owing  to  the  annoy- 
ing necessity  of  reference  to  complicated  tables  for  determining  the 
Relative  Humidity  and  Dew  Point  corresponding  to  the  difference  in 
degrees  between  the  wet  and  dry  bulb  thermometers  at  different  tem- 
peratures. 

The  Hygrodeik  chart,  while  complicated  in  appearance,  is  simplicity  itself, 
and  obviates  entirely  the  use  of  tables  for  temperatures  between  20° 
and  200°  F.  Full  instructions  with  each. $10.00

3375     MAGNIFIERS,  Doublet.    These  doublet  magnifiers  are  composed  of  two  sepa- 
rate piano  convex  lenses,  very  carefully  and  accurately  ground  and  polished, 
and  substantially  set  in  a  rich  black  lacquered  mount.    Types  B  and  C  are 
nickeled.    They  give  excellent  definition  and  an  exceptionally  flat  field  with 
greater  working  distance  than  is  usually  found  in  this  type  of  lens. 
Three  different  styles  of  mounting  are  offered,  according  to  the  different 
purposes  for  which  they  are  to  be  used. 
A — for  dissecting  stand. 
B — for  desk  use,  with  hexagonal  handle. 
C — in  folding  pocket  case.

3503  MOTOR,  Series  Intermittent  Service,  alternating  and  direct  current.  Machines 
or  devices  that  have  a  fixed  load  can  be  successfully  driven  by  series  type 
motors,  but  where  the  load  varies  and  it  is  necessary  to  maintain  a  con- 
stant speed  at  all  times,  regardless  of  the  load  fluctuation,  this  type  of 
motor  will  not  answer  the  requirements  fully.  For  uses  such  as  driving 
small  fans,  air  pumps,  centrifuges,  etc.,  these  little  motors  will  be  found 
preferable.

As  our  Ovens  are  made  in  our  shops,  v/e  are  prepared  to  make  them  in 
any  shape,  size  or  design  that  may  be  desired.  We  use  Heavy  Copper  for  all 
Ovens  coming  in  contact  with  water  or  the  moisture  from  steam,  when  steam 
heated.  All  Sheet  Metal  Ovens  other  than  those  which  must  be  of  Copper 
are  made  of  American  Ingot  Iron.  This  material  lasts  much  better  than  the 
Russian  Iron  or  plain  steel  which  pits.  For  the  outer  coverings  we  use  the 
Hard  finished  asbestos  product,  Transite,  which  is  the  best  known  insulator.

3583 


3582(c)  OVEN,  Sargent's  Electric,  patented  Jan.  6th,  1914;  electrically  heated  and 
automatically  controlled,  it  may  be  set  for  any  desired  temperature 
between  50°C  and  160°C,  and  is  accurate  to  within  1°C.  The  chamber 
of  the  oven  is  10  inches  high,  12  inches  wide  and  10  inches  deep.  The 
oven  is  made  of  an  asbestos  compound  and  bound  with  metal  and  may 
be  connected  to  the  usual  lamp  socket  by  a  plug  and  cord.  The 
units  are  of  the  replaceable  type  and  in  case  of  accident  may  be  renewed 
in  a  few  moments  without  the  use  of  tools.  The  working  chamber 
has  three  shelves,  of  which  the  two  upper  are  of  approximately  the 
same  temperature  and  are  usable  for  constant  temperature  work,  such 
as  coal  analysis,  while  the  bottom  shelf  being  close  to  the  heating 
units,  may  be  used  for  rapid  evaporations  where  the  temperature  is 
of  no  consequence,  as  in  inorganic  work. 
Arranged  for  110  or  220  volts,  direct  or  alternating  current. 
Price,  complete  with  thermometer,  six  foot  cord  and  plug  and 

directions  for  operating $27.50

3583  OVEN,  Celeritas,  Electric;  constructed  of  Asbestos  Board,  and  with 
heavy  brass  binding,  finished  in  keeping  with  our  regular  stand- 
ard apparatus.  The  regulation  is  positive  and  the  control  within 
one  degree.  The  range  at  which  the  Oven  can  be  used  is  from 
50  degrees  to  200  degrees  Celsius.  Consumption  is  5  amperes. 
Can  be  used  with  ordinary  socket  on  either  alternating  or  direct 
current.  A  feature  is  that  the  contact  points  are  outside  the  Oven. 
This  eliminates  any  possible  danger  when  using  a  combustible 
substance.  • 

Heating  units  are  independent  and  can  be  renewed,  but  this  will 
hardly  be  necessary  so  long  as  ordinary  care  is  taken  of  the  Oven. 
Electrical  heat  does  not  require  draft.    In  fact,  these  changes  are 
detrimental  to  all  heating  units.     Proper  ventilation  at  the  top  is 
all  that  is   necessary.

DEKHOTINSKY    TRIPLE  WALLED  DRYING  OVENS 


ELECTRICALLY  HEATED  AND  REGULATED 


3583-4 


3583-4     OVEN,  drying,  triple  walled   DeKhotinsky. 

Distinctive   Features. 

1.  A  new  bimetallic  thermo-regulator   (patent  applied  for),   which   is  actuated 
by    a    difference  in     temperature    of    1/°C.     (This    does    not    mean    control 
of  temperature  throughout  the  oven  chamber  to  1/4°  C,  but  within  the  space 
adjacent  to  the  regulator.)    Charts  made  with  a  recording  thermometer  actually 
show  less  than  a  degree  of  variation  through  periods  of  24  hours. 

2.  Location  of  the  heating  elements  in  the  base  of  the  oven  beneath  the  false 
bottom  —  instead  of  in  the  oven  chamber  —  where  they  are  shielded  by  an  iron 
deflector,  preventing  radiant  heat  from  striking  the  lower  shelf. 

3.  An  air  circulating  system  which  reduces  the  difference  in  temperature  between 
the   top   and   bottom   shelves   to   less   than   a   degree   C.   instead   of   12   to   20 
degrees,  as  usually  found. 

4.  The  DeKhotinsky  standard  system  of  heating,  by  which  extra  heating  units 
may  be  thrown  into  or  out  of  the  circuit  to  obtain  any  desired  temperature  up 
to  the  maximum. 

5.  Replaceability  of  heating  units  by  the  user  from  outside  the  oven  in  case  of 
burn-out,  at  a  nominal  cost,  without  the  necessity  of  interrupting  the  drying 
process  or  sending  to  the  factory  for  repairs. 

G.    Location  of  the  contact  points  of  the  make-and-break  outside  the  oven  and 
their  enclosure  in  a  tight  case,  preventing  any  possibility  of  the  explosion  of 
inflammable  gases  generated  within  the  oven. 

7.     Ease  of  adjustment  of  temperature,  by  means  of  the  thermo-regulator,  from 

room  temperature  to  the  maximum  temperature  of  the  oven.     This  is  accom- 

plished by  turning  a  removable  key  outside  the  oven,  actuating  a  worm  gear 

which  sets  the  contact  points  to  open  or  close  at  the  desired  temperature.

PAPER  TESTING  APPARATUS 


35S5 


3586 


3385  PAPER  TESTER,  Mullen  type,  for  testing  the  strength  of  paper,  fiber-board 
and  textiles.  This  instrument  accurately  and  automatically  registers  the 
strength  of  paper  in  pounds  to  the  square  inch.  The  paper  is  clamped 
over  one  end  of  the  cylinder  which  is  filled  with  liquid.  The  liquid  in 
this  cylinder  is  compressed  by  means  of  turning  a  handwheel  and  the  fluid 
is  forced  up  against  the  paper.  This  fluid  pressure  is  increased  until  the 
paper  is  burst.  At  the  breaking  point  the  gauge  pointer  remains  sta- 
tionary, so  the  results  can  be  read  closely.  Pressing  on  a  button  releases 
the  pointer.  Besides  its  use  on  all  kinds  of  paper,  fiber-board  and  so 
forth,  the  tester  is  used  on  such  materials  as  leather,  celluloid,  textile 
goods,  etc.  The  regular  size  tester  is  fitted  with  a  gauge  to  register  up 
to  160  pounds  per  square  inch,  although  it  is  advisable  to  use  lower 
reading  gauges  for  such  materials  as  tissue  or  .newspaper  and  a  higher 
reading  instrument  for.  boxboards  and  textile  goods  of  all  sorts. 
Paper  Tester,  Mullen  type $100.00 


3586  PRESSURE  BULKER,  Perkins'  type.  This  instrument  fills  a  very  definite  need 
by  providing  a  positive  uniform  standard  for  measuring  the  bulk  of  paper. 
A  pile  of  sheets  is  placed  between  the  contact  faces  and  the  handwheel 
clamp  is  screwed  down  until  the  desired  pressure  is  indicated  on  the 
dial.  The  thickness  can  be  read  directly  from  the  vertical  scale  at  the 
left.  The  pressure  is  indicated  in  pounds  per  square  inch  and  the  thickness 
in  inches  and  fractions  of  an  inch.  The  present  and  faulty  method  is 
to  caliper  one  sheet  and  multiply  by  the  number  of  sheets  in  a  pile  or 
package.  This  plan  affords  numerous  errors,  as  the  thickness  of  the 
paper  varies  so  much  that'  it  is  impossible  to  obtain  a  representative  sheet 
Pressure  Bulker,  Perkins'  type On  application 

We  have  the  facilities  for  furnishing  the  latest  types  of  paper  and  other  testing 
machines  and  do  not  purposely  list  at  this  time  such  instruments  which  are  imported 
and  which  are  unobtainable  at  this  period.  However,  upon  the  return  of  normal 
conditions,  we  can  furnish  any  of  the  imported  high  grade  testing  machines.

PLATINUM  SUBSTITUTES 

We  are  also  prepared  to  supply  any  articles  of  standard  shapes  and  sizes  of 
PALAU  WARE.  This  special  rare  metal  alloy,  developed  for  the  purpose  of 
replacing  expensive  platinumware,  contains  less  iridium  than  the  regular  platin- 
umware  usually  obtained  (report  of  Bur.  of  Stds.,  December,  1916),  is  guaran- 
teed to  withstand  continuously  1,300° C.,  and  has  been  used  by  prominent  chem- 
ists in  daily  laboratory  routine  and  in  varied  lines  of  work,  both  metallurgical 
and  industrial. 

BARIO  crucibles  can  also  be  furnished  by  us.  They  are  guaranteed  abso- 
lutely resistant  to  both  acid  and  alkali,  and  for  such  ordinary  laboratory  uten- 
sils are  equal  to  platinumware  and  cost  but  a  small  fraction  as  much.

PUMPS— CENCO-NELSON  HIGH  VACUUM 

These  pumps  represent  the  most  recent  development  in  High  Vacuum  Pumps  for 
laboratory  and  commercial  purposes.  They  are  compact,  operate  with  very  small  ex- 
penditure of  power,  require  no  attention  when  in  operation  and  should  last  indefinitely. 
They  measure  about  seven  inches  high  by  five  inches  in  diameter  at  the  base  and  weigh 
approximately  ten  pounds.  The  pulley  is  grooved  for  %-inch  round  belt. 

Under  favorable  conditions,  a  vacuum  of  0.1  mm.  may  be  obtained  with  the  Two- 
stage  Pump.  On  continuous  service,  some  heating  takes  place,  which  lowers  the  vacuum 
somewhat.  With  the  Three-stage  Pump,  water  cooled,  a  vacuum  of  .05  mm.  may  be 
obtained  by  using  proper  precautions. 

The  displacement  of  these  pumps  in  free  air,  according  to  tests  in  our  laboratory, 
is  approximately  285  cu.  in.  per  minute,  or  10  cu.  ft.  per  hour,  at  a  speed  of  900  r.  p.  m. 

They  will  evacuate  a  flask  of  one  liter  capacity  to  a  vacuum  of  1  mm.  in  two  minutes.

LABORATORY  SUPPLIES  AND  CHEMICALS 


The  valuable  optical  properties  of  quartz  crystal,  recognized  for  hundreds  of  years, 
were  responsible  for  the  earliest  attempts  to  fuse  this  material  into  a  homogeneous 
glass.  Although  most  entirely  without  success  for  many  years,  these  early  efforts 
revealed  the  special  physical  qualities  of  Quartz  Glass,  which  have  since  secured  for 
it  such  an  important  position  among  laboratory  apparatus.  Its  melting  point  lies 
800°C  (1400°F.)  higher  than  that  of  common  glass,  and  it  may  be  subjected  without 
misgiving  to  the  greatest  and  most  sudden  temperature  changes.  The  coefficient  of 
expansion  of  Quartz  Glass,  between  0-1000°  C  is  0,00000054;  i.  e.,  a  rod  of  Quartz 
Glass  1  meter  long  at  0°C  expands  0.54  mm.  when  heated  to  1000°C.

Sampler   Imbedded   in   Coal 


3671(b) 


SAMPLER,  "comTeco"  Reliable  Coal  Sampler.  Decidedly  practical  for  coal 
sampling  from  cars  and  piles.  Devised  so  as  to  sample  coal  that  is  3  inches 
or  smaller  in  diameter.  The  simple  construction  makes  it  practical  and  easy 
to  operate. 

The  cut  shows  the  sampler  imbedded  in  the  coal.  The  sample  has  been 
extracted  from  top  to  bottom  of  the  coal  as  it  lies  in  the  car.  This  is  the 
true  way  of  obtaining  a  thoroughly  representative  sample.  The  pipe  thus 
surrounds  the  sample  and  keeps  it  intact  until  it  is  withdrawn  from  the 
coal.  Then,  by  reversing  the  spiral,  the  sample  of  coal  is  emptied  into  a 
receptacle  suitable  for  that  purpose.  The  teeth  at  the  bottom  of  the  pipe 
act  as  "grippers,"  thus  keeping  the  pipe  from  turning.  These,  together 
with  the  spiral,  act  also  as  a  "clipper"  and  shear  off  pieces  of  coal  that 
wedge  between.

"SAFETY  FIRST  DEVICES" 

It  is  estimated  that  in  this  country  60%  of  accidents  are  due  to  negligence 
on  the  part  of  employers  and  employees  and  40%  to  the  inevitable  risks  of 
employment.  It  is  generally  estimated  that  about  500,000  persons  are  yearly 
killed  or  incapacitated  by  industrial  accidents,  entailing  a  loss  in  earning 
power  of  at  least  $250,000,000  per  year.  It  is  necessary,  therefore,  that  atten- 
tion be  given  to  prevent  such  accidents.  There  are  thousands  of  men  in 
the  industries  who  are  liable  to  injury  and  a  large  percentage  of  these  may 
escape  injury  by  equipping  themselves  with  safety  devices.  If  an  injury  is 
received,  knowledge  and  immediate  accessibility  to  first  aid  appliances  will 
greatly  diminish  disabilities  and  deaths. 

Therefore,  for  those  who  are  engaged  in  hazardous  occupation  we  are 
listing  complete  lines  of  helmets,  respirators,  goggles,  asbestos  gloves  and 
suits,  rubber  gloves,  safety  first  cabinets,  and  so  forth.  The  articles  are 
scientifically  correct  and  their  plan  of  use  is  based  upon  the  highest  principles 
of  humanity. 


GOGGLES  AND  SPECTACLES 

In  many  industries,  goggles  are  absolutely  indispensable.  Chemists  and  all  other 
workers  who  are  subjected  to  injury  from  flying  particles  or  poisonous  fumes  require 
goggles  made  especially  for  their  particular  work.

SPECTROSCOPES  AND  ACCESSORIES 

We  are  capable  of  supplying  any  of  the  standard  American  made  spectroscopes. 
Below  we  list  a  type  of  spectroscope  which  is  in  general  use  in  laboratories  today. 
The  smaller  instrument  is  especially  adapted  for  school  use.  Any  apparatus  embodying 
special  optical  features  can  be  furnished  upon  receipt  of  specifications.  Estimates 
cheerfully  given  on  any  optical  instruments,  and  repair  of  same. 


3810-1 


3810-1  SPECTROSCOPE.  The  usual  standard  type  fitted  with  collimator, 
observing  telescope  and  scale  tube.  The  collimator  is  stationary  and 
fitted  with  adjustable  slit  having  jaws  of  German  silver.  The 
observing  telescope  has  coarse  adjustment  only  around  the  axis. 
Both  collimator  and  observing  telescope  are  fitted  with  achromatic 
objectives  of  25  mm.  aperture.  The  other  necessary  adjustments 
for  adjusting  the  tubes  in  horizontal  position  are  provided.  This 
instrument  is  now  furnished  with  a  liquid  prism  for  bi-sulphide  of 
carbon,  but  provision  is  made  for  adjusting  scale  tube  and  observing 
telescope  so  that  other  prisms  of  any  dispersion  may  be  used.  The 
cost  of  the  instrument  including  prism  is $48.00 

Accessories  for  this  instrument: 

1st.     Comparison  Prism  for  Slit $  5.00 

2nd.     Rack  and  Pinion  Motion  for  Slit 5.00 

3rd.     Slow  Adjustment  for  observing  telescope  (tangent  screw) 5.00 

4th.     Illuminating  Burner  (gas)  for  scale  tube  or  collimator 3.00 

3810-2     Is  a  less  expensive  instrument  for  school  use  which  is  smaller,  but  other- 
wise of  the  same  type  as  No.  3810-1.

Outlet 


3811 

3811  STILL,  Stokes'  Automatic.  By  a  clever  construction  this  Still  accomplishes 
several  novel  results.  First,  it  utilizes  the  heat  generated  in  the  Still 
for  pre-heating  the  incoming  water  to  the  boiling  point  and  thus  a  small 
quantity  will  operate  the  Still  after  it  is  once  started.  Second,  by  pre- 
heating the  feed  water  before  it  enters  the  distilling  basin,  the  ammonia 
and  other  gases  due  to  impurities  in  the  raw  water,  are  liberated  and  escape 
into  the  air  through  an  opening  provided  for  this  purpose.  Third,  the 
condenser  tubes  extend  to  the  extreme  top  of  the  steam  chamber,  high 
above  the  water  level,  so  there  is  no  danger  of  the  raw  water  being  carried 
over  by  the  steam.  Fourth,  the  Still  can  be  easily  cleaned  by  opening 
the  valve  connecting-  with  the  drain  and  flushing,  or  by  removing  the  lid 
on  top  and  scrubbing.  The  copper  steam  coil  can  also  be  easily  discon- 
nected for  the  removal  of  scale  in  case  the  feed  water  deposits  same.

THE  IMPROVED  "ROCHLITZ"  AUTOMATIC  WATER  STILL 


3812 


3812(a) 


It  is  well  known  that  the  absorptive  power  of  distilled  water  is  second  to  only 
that  of  acids.  All  but  the  precious  metals  and  block  tin  are  susceptible  to  its  action, 
and  if  it  comes  in  contact  with  tanks,  or  pipes  of  other  metals,  it  will  be  found  to  con- 
tain slight  quantities  of  them  in  solution.  In  order  to  render  this  contamination 
impossible,  the  "Rochlitz"  Automatic  Water  Stills  are  lined  throughout  with  purest 
block  tin. 

3812  STILL,  Automatic,  Gas  operated  (Rochlitz  improved).  Simple  in  construc- 
tion. All  parts  readily  accessible  for  cleaning  when  desired.  Easily  oper- 
ated and  guaranteed  to  give  entire  satisfaction.  This  still  is  the  Rochlitz 
Still  greatly  improved  and  enlarged,  made  of  copper  and  brass  throughout, 
tin  lined  inside  so  that  the  water  comes  in  contact  with  the  tin  only.  The

STIRRER,  GRAMERCY  ELECTRIC 

This  excellently  designed  apparatus  will  be  found 
useful  for  a  number  of  purposes  besides  general 
stirring.  The  motor  is  fitted  with  a  pulley  wheel, 
which  can  be  brought  to  a  vertical  position  by  a  turn 
of  the  adjustable  extension  clamp  attaching  the  mo- 
tor to  the  support  and  allowing  the  motor  to  be 
raised  or  lowered,  as  may  be  desired. 

The  removable  attachment  holding  the  stirring 
rod  is  provided  with  a  union  fitting,  which  firmly 
holds  the  stirrer  and  allows  it  to  be  quickly  and 
easily  removed.  The  Universal  Motor,  1*5  H.  P., 
which  can  be  operated  on  either  D.C.  or  A.C.,  is 
fully  enclosed  with  an  aluminum  cover  to  prevent 
dust  or  particles  from  getting  to  the  working  parts. 
It  is  attached  to  the  support  by  means  of  an  ad- 
justable extension  clamp.  The  heavy  iron  support, 
with  base  16  cm.  x  25  cm.,  is  fitted  with  a  hollow 
upright  through  which  passes  the  wires  from  the 
rheostat  to  the  motor,  which,  above  the  rod,  are 
sheathed  in  flexible  metallic  tubing.  A  rheostat,  hav- 
ing ten  steps,  is  neatly  fitted  under  the  base  of  the 
support.

3996A     SINGLE  STRAND  TESTERS.     Hand  operated.     In  the  use  of  some  materials 
it   is   advisable   to   know  the   strength   of  the   individual   strand.    The    two 
machines  shown  above  are  made  to  be  driven  by  hand.   The  recording  head 
is   built   as    a   balance   wheel    rotating    upon    two    large    self-aligning   ball- 
bearings in  such  a  manner  as  to  be  extremely  sensitive. 
No.  3996A.     Capacity — 10  pounds  by  ounces. 
No.  3996B.     Capacity — 50  pounds  by  J4   pounds. 

3997A.  YARN  TESTER.  Hand  operated.  This  machine  is  a  development  of  the 
old  English  yarn  tester.  When  a  sample  has  been  placed  upon  the  yarn 
hooks  the  hand  wheel  is  rotated  until  the  break  occurs.  This  strain  causes 
the  weight  to  swing  outward  away  from  its  vertical  position  and  the  pawl 
on  the  lever  below  the  weight  holds  it  in  this  position  until  reset  by  the 
operator.  Also  furnished  in  power  driven  types.  Capacity  up  to  250  pounds. 


3997B  CLOTH  TESTER.  Hand  operated.  Produced  to  satisfy  the  demand  for  a 
quickly  and  easily  operated  cloth  tester.  Capable  of  a  great  range  of  work. 
Operated  on  the  principle  applying  to  the  above  yarn  tester.  Also  fur- 
nished power  operated. 

All  of  the  textile  testers  listed  above  require  the  use  of  specially  designed 
clamps.  We  are  prepared  to  furnish  clamps  for  any  of  the  testers  as  well 
as  any  special  clamps  which  might  be  necessary  for  a  particular  test.  All 
testers  and  equipment  are  made  according  to  U.  S.  Standards  and  are 
interchangeable.  Fully  guaranteed  for  accuracy,  design,  material  and  work- 
manship.

COMBINATION  POWER  YARN  AND  CLOTH  TESTER 


3997C  This  tester  is  a  combination  of  the  machines  listed 
on  the  previous  page.  The  addition  of  the 
automatic  recorder  has  greatly  enhanced  the 
value  of  the  tester.  By  the  use  of  the  recordjer 
a  chart  line  indicative  of  stretch  and  strength 
of  the  material  is  automatically  recorded.  The 
chart  line  shows  the  exact  relation  of  stretch 
to  the  tensile  strength,  at  every  point  of  the 
test.  Aeroplane  wing  fabric  and  other  mate- 
rials whose  elongatiln  under  certain  tension 
is  of  vital  importance  can  be  accurately  tested 
only  by  this  means. 

Can  be  supplied  in  sizes  of  50  to  600  pounds 
capacity  depending  upon  the  kind  of  material 
to  be  examined.

=  1-4  oz.   (avoir'pois). 

=  1-2  oz. 

=  1  oz. 

=  16  ozs.  (avoir.)  or  1  Ib. 


Measurements  Used  for  Cotton  Yarns 

54  inches  =      1  thread  or  circumference  of  hank. 
4,320  inches  =    80  threads  =  120  yards  —  1  lea. 
30,240  inches  =  560  threads  =  840  yards  =  1  .hank. 
No.  of  yards-=-8.33  grains=counts  of  yarn. 
1  bundle  usually  =  10  Ibs.  weight. 

Worsted  Yarns 

In  its  general  features  the  system  of  numbering  worsted  yarns  are  similar  to  those 
of  cotton.   The  worsted  reel  is  two  yards  in  circumference,  and  the  table  of  measure  is: — 
2  yds.  =     1  thread. 
80  yds.  =  40  threads  =  1  lea  or  warp. 
560  yds.  =280  threads  =  7  lea  or  warp  =  1  hank. 

12  hanks  =    1  doz. 
144  hanks  —  12  doz.  =  1  gross. 

THE  COUNTS  OF  YARN  is  the  number  of  hanks  required  to  weigh  1  Ib.  avoirdupois 
(or  7,000  grains  Troy). 


RULE  FOR  COUNTS — Reel  off  and  weigh  a  suitable  number  of  leas,  add  3  cyphers 
to  number  of  leas  weighed,  and  divide  by  number  of  grains  (Troy)  the 
yarn  weighs;  the  result  gives  the  counts.

3998A  YARN  REEL.  The  reel  is  54  inches,  or  one  and  a  half  yards,  in  circumference.  The  dial 
is  graduated  into  120  parts,  indicating  the  number  of  yards  reeled  from  each  spin- 
dle. The  yarn  guides  and  spindles  are  kept  in  line  with  each  other  while  feeding 
yarn  upon  the  reel,  which  is  very  desirable  when  reeling  fine  yarns.  The  extra  length 
of  yarn  guides  is  of  use  in  increasing  the  friction  upon  the  yarn  by  taking  a  half  turn 
or  more  of  yarn  aroutid  them.  The  automatic  feed  motion  lavs  the  yarn  flat  upon 
the  reel,  thus  securing  accurate  and  uniform  measurement,  and  consequently  correct 
results  as  to  stretch,  strength  and  numbering.  The  bright  spot  on  the  web  of  the 
worm  wheel  is  to  show  when  the  zero  upon  the  dial  approaches  the  index  point,  and 
thus  assists  the  operator  to  stop  promptly  on  the  striking  of  the  bell.  Made  in  four 
or  seven  spindles. 

3998B  UMBRELLA  REEL.  This  reel  can  be  furnished  with  an  adjustable  clamp  base  for 
attaching  to  the  edge  of  a  table  or  shelf  of  any  thickness.  All  parts  are  of  metal  and 
those  coming  in  contact  with  the  yarn  are  of  solid  brass  and  very  smooth.  It  will 
hold  skeins  up  to  72  inches  and  is  invaluable  for  winding  or  exa'mining  yarns.

3999A  ROVING  OR  YARN  SCALES.  This  scale  will  weigh  one  pound  by  tenths  of  grains,  or 
one  seventy-thousandth  part  of  one  pound  avoirdupois,  rendering  it  especially  well 
adapted  for  use  in  connection  with  Yarn  Reels,  for  the  numbering  of  yarn  from  the 
weight  of  hank,  giving  the  weight  in  tenths  of  grains  to  compare  with  tables.  It  is 
also  useful  for  the  weighing  of  any  small  articles,  coolrs,  drugs,  etc.,  for  computation 
of  large  quantities,  or  for  postal  scales.  The  finished  parts  are  nickel-plated  and 
the  stand  japanrted  and  ornamented.  Ten  balancing  weights  accompany  each  scale, 
viz.:  one  each  of  20,  30,  60,  100,  200,  300,  500,  1000,  2000  and  3000  grains;  the  20 
grains  on  the  beambeing  each  divided  into  10  parts.  A  level  glass,  to  aid  in  adjust 
ment,  is  set  in  the  base. 

3999B  YARN  INSPECTOR.  For  comparing  and  examining  fine  or  coarse,  cotton,  woolen,  silk, 
jute  or  other  yarns.  The  cut  shows  a  machine  with  inspection  board  in  position. 
The  yarn  is  wound  from  two  cops  or  spools,  and  is  laid  evenly  in  parallel  lines  upon 
boards  17%  inches  long  by  8  inches  wide.  These  boards  are  held  in  the  machine  by 
a  spring  clamp  and  are  instantly  interchangeable.  Defects  of  any  kind  are  readily 
exposed  and  samples  may  be  held  on  file  indefinitely  for  future  reference  and  compari- 
son. Twelve  boards  are  furnished  with  each  machine  and  extra  boards  will  be  sup- 
plied when  desired.  The  machine  is  mounted  upon  a  well-finished  weathered  oak 
base  and  designed  with  two  solid  iron  side  frames  which  support  the  mechanism. 
All  metal  parts  are  finished  in  black  enamel  and  nickel  plate,  making  this  machine 
very  attractive  as  well  as  serviceable. 


3999C  TWIST  COUNTER.  This 
machine  is  designed  for 
ascertaining  the  number 
of  twists  in  yarn.  Samples 
from  one  to  ten  or  twenty 
inches  can  be  clamped  in 
the  jaws  provided  for  the 
purpose  and  by  revolving 
the  hand  wheel  until  th1? 
yarn  lays  straight  and  the 
strands  are  parallel,  th«> 
dial  will  accurately  record 
the  number  of  twists  un- 
raveled.

The  Thermit  reaction  is  based  on  the  chemical  formula  Fe2O3+2Al=2Fe-j-Al2O». 
In  other  words,  iron  oxide  mixed  with  aluminum  in  approximately  volumetric  pro- 
portions and  in  the  proper  state  of  division  will  react  in  such  a  way  that  the  oxygen 
leaves  the  iron  oxide  and  combines  with  the  metallic  aluminum  with  which  it  forms 
an  aluminum  oxide  or  slag,  setting  free  the  iron. 

The  essential  characteristic  of  the  process  is  that  when  the  Themit  mixture  is 
ignited  in  one  spot,  the  combustion  so  started  continues  throughout  the  entire  mass 
without  supply  of  heat  or  power  from  outside,  and  produces  superheated  liquid  steel 
and  superheated  liquid  slas?.  The  temperature  produced  by  the  reaction  attains  about 
4881°  F  in  less  than  thirty  seconds.  The  liquid  steel  produced  by  the  Thermit 
reaction  represents  one-half  of  the  original  Thermit  by  weight  and  one-third  by 
volume. 

. In  order  to  ignite  Thermit,  place  on  top  of  it  a  small  heap 

of  special  ignition  powder.  Place  on  top  of  the  powder  a 
parlor  match,  so  that  the  head  of  it  will  come  about  over  the 
center  of  the  powder,  ignite  the  head  of  this  match  by  applying 
another  parlor  match.  Care  must  be  taken  as  the  reaction 
takes  place  instantaneously. 
Welding  a  Small  Boss  to  a  Steel  Plate  by  Igniting  the  Thermit  Directly  on  the  Plate 

The  materials  necessary  are 
a  steel  plate,  a  refractory 
pouring  cup,  the  necessary 
quantity  of  Themit  (welding 
portion  No.  1  in  can)  and 
one-half  teaspoonful  of  igni- 
tion powder.  Place  the  plate 
on  some  dry  sand  and  put  one 
of  the  pouring  cups  anywhere 
on  the  plate  after  taking  care  that  the  place  selected  is  free  from  dirt  or  rust.  Then 
fill  the  pouring  cup  about  half  full  of  Thermit  and  ignite  as  described  above.  The 
Thermit  will  burn  down  rapidly,  giving  off  a  bright  light.  It  is  advisable  to  protect 
the  eyes  with  dark  glasses.  When  the  reaction  has  been  well  started,  feed  in  the 
balance  of  the  Thermit  from  the  can  in  a  steady  stream  so  as  to  keep  the  reaction 
going  until  the  entire  welding  portion  has  been  consumed.  About  two  minutes 
after  the  experiment  has  been  made,  tap  the  pouring  cup  gently  with  a  hammer  so  as 
to  break  it  up.  It  will  be  found  that  a  lump  of  steel  has  been  welded  to  the  plate. 
Materials  required:  A — 3/16"  steel  plate.  D — 2  pouring  cups.  J — 2  cans  Thermit 
and  can  of  powder. 

Burning  a  Hole  Through  a 
Plate 

This  experiment  demon- 
strates the  intense  heat  con- 
tained in  the  Thermit  steel 
and  incidentally  teaches  the 
proper  manner  of  closing  the 
outflow  of  the  crucible  (plug- 
ging the  tap  hole)  and  tap- 
ping the  same  when  the  re- 
action is  completed.

VOLUME  OF  LOAF  APPARATUS 

Two  aluminum  receptacles,  connected 
with  a  graduated  tube,  are  suitably 
mounted  on  a  pedestal  and  pivoted  in 
the  center  for  reversing  the  alternate 
ends.  A  funnel  orifice  in  the  center 
of  the  tubing  causes  the  seed  to 
flow  uniformly  from  the  top  to  the 
bottom  receptacle  like  an  hour-glass. 
This  mechanical  filling  of  the  lower 
receptacle  insures  the  same  degree  of 
compactness  under  all  conditions, 
therefore,  machine  accuracy.  To 
operate  the  measure,  the  lid  of  the 
top  receptacle  is  removed,  mustard 
seed  is  poured  in  until  the  standard 
quantity  is  registered.  The  loaf  is 
secured  to  the  top  lid  by  a  spring 
clamp;  the  lid  is  then  replaced  and 
the  position  of  the  two  receptacles 
reversed;  the  seed  flowing  through 
the  orifice  in  the  center  of  the  tubing 
fills  in  around  the  loaf  in  the  bottom 
receptacle.  The  amount  of  seed  dis- 
placed registers  the  volume  of  the 
loaf  on  the  tubing,  graduated  in 
cubic  centimeters.  The  operation  is 
repeated  \v;lh  additional  loaves,  using 
the  alternate  receptacles.  The  recep- 
tacles are  made  to  accommodate  the 
regular  commercial  pound  loaf.

TEST  TUBE  OR  BOTTLE  WASHER 


4233 

The  above  illustration  shows  the  Washer  made  with  24  Washing  Tubes.  Twelve 
8"  and  twelve  12".  Dimensions  over  all  14"xl7".  Two  Control  Cocks. 

This  Washer,  designed  for  the  Johns  Hopkins  Hospital,  enables  one  to  rapidly 
Cleanse  Test  Tubes  of  all  lengths,  the  longer  Tubes  being  suitable  for  washing  any 
tube  up  to  14"  long,  as  the  water  when  turned  into  the  High  Tube  section  by  turning 
off  the  low  service  will  spout  six  or  more  inches  in  the  air.  The  whole  24  Tubes  can 
be  used  where  there  are  only  short  tubes  to  be  washed  and  if  the  head  of  water 
has  sufficient  pressure. 

The  waste  water  will  run  off  the  Washer  into  the  sink  at  the  vent  shown  at  the 
opposite  end  from  the  Control  Cocks. 

Hot  or  cold  water  can  be  used  as  desired.     The  inlet  is  at  opposite   end  from 
the   Control    Cocks,   and   we   furnish   ample   length   Heavy   Rubber    Hose    to   connect 
to  the  usual  water  supply. 
Price $45.00 

We  are  listing  the  above  test  tube  washer,  which  we  consider  is  an  essential  in 
a  laboratory  of  any  size.  This  washer  is  also  adapted  for  washing  such  articles  as 
Babcock  Milk  and  Cream  Testing  Bottles.  The  apparatus  washes  both  short  and 
long  tubes.  Also  furnished  for  tubes  of  6,  8,  10  and  12"  lengths,  with  a  control  cock 
for  each  size  of  tube.  Prices  for  types  other  than  the  one  herein  listed  upon  request.

^jjjnjrjjjfr     .  drum,  having  a  nickel-plated  metal  body 

with  a  top  and  bottom  of  J4-inch  trans- 
ite.  The  dimensions  of  this  drum  are: 
height,  2l/4  inches;  diameter,  3l/2  inches. 
The  apparatus  is  mounted  upon  three 
leg's. 

Located  near  the  center  of  the  drum 
there  is  a  metal  cup  or  cylinder  1 1/16 
inches  in  diameter  and  \l/2  inches  in 
depth.  This  is  the  heating  receptacle. 
The  cup  is  encased  in  a  resistance 
coil,  which  provides  equal  distribution 
of  heat  to  the  entire  surface  of  the 
receptacle  simultaneously,  heating  it 
uniformly  and  very  quickly. 

This  resistance  coil  or  heating  unit 
is  controlled  by  an  automatic-electro 
thermo-regtilator,  contained  within  the 
drum.  It  is  adjusted  by  means  of  a 
small  screw.  To  reach  the  adjusting 
screw  of  the  thermostat  it  is  necessary 
to  use  a  small  screwdriver.  This  pre- 
vents tampering. 

The  thermo-regulator  completely  con- 
trols the  temperature  so  that  the  con- 
tents of  the  test  tube  may  be  brought 
to    the    boiling    point    without    boiling 
over.     Metal  rings  are  provided  for  the 
receptacle,    permitting   the   use    of   the 
following  sizes  of  test  tubes:   Yz   inch, 
•Hs  inch,  y±  inch,  and  1  inch. 
Price,     complete,     including     test 
tube    and    small    crucible,    as    per 
4235  illustration    $10.00

These  indicators  are  manufactured  in  a  spirit  of  co-operation  with  medical  research, 
rather  than  for  profit.  It  is  desirable,  therefore,  to  distribute  them  in  quantities  of  not 
more  than  five  decigrams  to  a  large  number  of  investigators.  In  special  instances,  larger 
quantities  may  be  obtained,  should  they  be  actually  needed,  and  in  the  future,  if  large 
quantities  of  the  indicators  are  required,  the  demand  will  be  met.

BACTERIOLOGICAL  AND   MICROSCOPICAL   APPARATUS 


5000 


5000  AUTOCLAV  OR  DIGESTER,  "Eclipse"  Patented,  Made  of  extra  heavy  copper 
and  brass  throughout,  no  iron  or  other  metal  to  rust  or  corrode.  The 
ingenious  construction  of  the  door,  which  is  of  cast  brass  and  is  convexed 
to  maintain  perfect  symmetry  of  the  body.  When  opened,  it  fits  snugly 
the  inside  body  of  this  sterilizer,  leaving  the  entrance  and  interior  en- 
tirely clear. 

The  door  and  head  are  perfectly  ground  and  fitted,  requiring  no  packing 
or  gaskets,  which  are  always  a  source  of  considerable  annoyance  and 
expense.  The  Eclipse  sterilizers  have  no  locks  or  spring  on  the  door.  No 
device  to  get  out  of  order. 

They  may  be  opened  or  closed  instantly  without  effort. 

It  is  impossible  to  open  the  door  while  there  is  the  slighest  pressure  in 
the  interior,  and  there  is  never  any  danger  of  scalding.  We  emphasize 
this  statement  as  numerous  accidents  have  occurred  with  faulty  mechan- 
ical arrangements  on  sterilizer  doors  or  leaky  gaskets. 

The  steam  fills  the  outer  jacket  and  enters  the  inner  chamber  at  once. 
This  operation  prevents  the  contents  from  becoming  moist  by  the  con- 
densed steam. 

Can  be  used  as  a  free  steam,  non-pressure  sterilizer  by  opening  the  air 
cock  if  desired.  Mounted  on  white  enameled  stand.  Heated  by  Steam, 
Gas,  Gasoline  or  Petroleum.

LABORATORY  CAGES 

We  furnish  bacteriological  laboratories  with  all  types  of  cages.  They  are  con- 
structed of  various  materials  depending  upon  the  use  to  which  the  cage  is  to  be 
put.  These  cages,  of  which  only  a  few  are  listed,  are  used  for  breeding  purposes 
and  for  the  close  observation  of  animals  used  as  subjects  in  innoculations  and  so 
forth.  Each  cage  is  designed  to  fit  the  particular  animal  under  study,  as  the  cat, 
dog  and  rodent.  All  cages  are  made  so  that  they  may  be  easily  and  quickly  cleaned, 
and  many  are  collapsible  for  storage  and  convenience  in  sterilizing.  We  shall  be 
pleased  to  furnish  detailed  description  and  prices  of  any  type  not  listed  below. 
Any  special  type  involving  new  ideas  can  be  furnished  by  us  with  price  upon  appli-

The  Levy  Counting  Chambers  possess  the  following  distinct  characteristics: 

Increased  visibility  of  the  rulings  when  chamber  is  filled  with  solution. 
The  new  method  of  construction  entirely  avoids  the  cemented  cell  and  the 
attendant  danger  of  its  looseniqg  by  the  drying  out  of  the  balsam  cement, 
and  the  possibility  of  the  loosening  of  the  ruled  counting  surface  is  also 
greatly  reduced  by  this  construction. 

The  parallel  form  of  cell  first  suggested  by  Biirker  and  used  in  all  Levy 
counting  chambers  provides  a  more  uniform  distribution  of  corpuscles  over 
the  ruled  area  and  entirely  removes  the  effect  of  atmospheric  pressure 
upon  the  depth  of  the  solution,  a  souce  of  considerable  error  in  the 
circular  form  chambers.

DOUBLE  COUNTING  CHAMBERS— We  especially  recommend  the  use  of 
the  double  chamber,  in  which  the  rectangular  strip  in  the  center  of  the  cell  is  divided 
by  parallel  moats  and  each  half  provided  with  a  Neubauer  ruling,  so  that  both  red  and 
white  counts  may  be  made  at  the  same  time  without  the  necessity  of  cleaning  and 
refilling  the  counting  chamber.  This  double  type  of  counting  chamber  has  been  for 
several  years  used  in,  and  recommended  by,  the  clinical  laboratories  of  the  Johns 
Hopkins  Medical  School  and  has  been  recently  purchased  in  large  quantities  by  the 
U.  S.  Army  Medical  Department,  and  is  rapidly  coming  into  wide  use  because  of  its 
convenience.

cubating chamber  increases  in  size,  the  question  of  proper  ventilation 
becomes  a  most  important  factor.  The  steel  chimneys  which  are  used 
for  protection,  start  a  rapid  motion  of  the  air,  thus  stimulating  cir- 
culation of  the  air  currents,  as  soon  as  the  electric  current  is  turned 
on.  This  is  just  the  incubator  for  a  small  laboratory.

ELECTRIC  INCUBATORS  WITH  DRAWER  COMPARTMENTS 

The  Compartment  Incubator  is  manufactured  in  three  sizes  to  contain  either  24, 
36  or  48  drawers. 

The  idea  is  to  furnish  a  separate  drawer  or  compartment  for  the  individual  use 
of  each  student. 

Inside  dimensions  of  each  compartment:  Height,  6  inches;  width,  5  inches;  depth, 
18  inches. 

The  Incubators  are  heated  with  lamps  provided  with  steel  chimneys  for  protection, 
or,  if  preferred,  electric  heating  units  with  pilot  lamps.  Controlled  by  our  latest 
automatic  electro-thermostats. 

The  drawers  rest  upon  steel  frames  and  the  entire  Incubator  is  lined  inside  with 
animal  hair  and  transite  for  perfect  insulation  t  and  to  guard  against  fire. 

These  drawers  are  made  of  perforated  galvanized  steel  so  as  to  permit  the  heated 
air  currents  to  circulate  freely  through  all  the  compartments. 

Proper  ventilation  and  air  circulation  have  required  much  careful  investigation. 
These  questions  had  to  be  settled  by  actual  test,  to  the  end  that  each  and  every  com- 
partment might  retain  its  proper  degree  of  temperature  relatively. 

The  cabinets  are  mounted  on  angle  iron  stands  to  raise  them  to  a  convenient  height 
from  the  floor. 

It  is  the  ideal  Incubator  for  Universities,  Colleges,  Schools  or  wherever  cultures 
are  made. 

6128  INCUBATOR — Twenty-four  drawer  compartments.  Outside  dimensions 
of  cabinet:  Height,  41  inches;  width,  42  inches;  depth,  23^4  inches.

8134  Combined  Electric  Incubator  and  Paraffin  Oven.  The  above  illustration  repre- 
sent an  apparatus  both  unique  and  practical  in  Electrical  Laboratory 
Equipment. 

The  size  and  construction  is  the  same  as  in  our  No.  6133  Electric  In- 
cubator, except  that  a  dividing  partition  has  been  added,  which  separates 
the  compartment  into  two  chambers  of  equal  size  of  the  following  dimen- 
sions: Height,  30  inches;  width,  17^  inches,  depth,  18  inches. 

The  partition  is  made  of  cork  1  inch  thick,  protected  on  each  side  with 
a  layer  of  transite;  the  whole  being  1%  inches  thick. 

This  construction  insures  perfect  insulation  between  the  two  chambers, 
to  the  end  that  both  may  be  used  simultaneously — one  for  incubation  and 
the  other  for  paraffin  work. 

Each  chamber  is  supplied  with  its  own  heating  units,  pilot  lamp  and 
Electro-Thermostat,  thus  permitting  the  use  of  either  chamber  irrespective 
of  the  other. 

The  Paraffin  Oven  contains  Paraffin  Receptacle  (see  description), 
which  is  provided  with  five  shelves,  each  having  nine  holes  2tV  inches  in 
diameter  for  paraffin  dishes,  thus  affording  large  capacity  for  work. 

This    Combination    Incubator   and   Paraffin   Oven   not   only   represents 
economy  of  space,  but  also  obviates  the  necessity  of  having  two  separate 
pieces  of  laboratory  apparatus.     It  is  supplied  with  an  angle  iron  stand  32 
inches  high  and  with  thermometer  for  each  compartment.

6136     ELECTRIC  INCUBATOR,  for  Maintaining  the  Entire  Microscope  at  a  Constant 

Temperature.  For  those  desiring  to  make  a  special  study  of  Micro-organ- 
isms at  blood  temperature  for  any  length  of  time,  we  have  constructed  a 
special  Incubator,  in  which  the  entire  microscope  may  be  placed.  Both 
sides  arc  provided  with  hand  holes,  which  enable  the  operator  to  manipu- 
late the  microscope  in  the  ordinary  way.  When  not  in  use  the  hand  holes 
are  closed  by  metal  slides. 


The  Incubator  is  made  of  insulating  material  and  has  a  removable 
plate  glass  front.  A  Bausch  &  Lomb  B  B  H  miscroscope,  which  is  shown 
outlined  in  the  cut,  requires  an  Incubator  7  inches  x  7^  inches  x  9  inches 
deep  inside  dimensions. 


Where  the  size  of  the  microscope  is  similar  to  above,  no  extra  charge 
will  be  made,  but  should  the  size  of  the  microscope  necessitate  a  consider- 
able change,  such  alterations  will  be  charged  for  accordingly. 


.  This  Incubator  is  particularly  well  adapted  for  universities  and  research 
laboratories.  It  is  used  to  advantage  in  watching  developments  of  Em- 
bryos of  animal  parasites  and  also  in  watching  the  growths  of  normal  and 
abnormal  tissues.  It  is  convenient  in  bacteriological  and  zoological  research 
work  and  in  research  work  on  blood.  An  apparatus  like  this  opens  up 
many  new  lines  of  research.

6138  ELECTRIC  INCUBATOR,  for  the  Microscope  Stage.  This  warming  stage  is  a 
miniature  Incubator  complete  in  itself.  It  fits  the  mechanical  stage  of  any 
standard  microscope. 

The  outside  dimensions  are  3^  inches  x  2  inches  x  Yz  inch  in  thick- 
ness. The  incubating  chamber  measures  3  inches  x  1  inch  x  Yz  inch  in 
depth  and  has  a  removable  glass  bottom  consisting  of  a  regular  3x1  slide. 
The  specimen  to  be  examined  is  placed  on  this  slide.  The  condenser  may 
thus  be  brought  up  close  to  the  glass,  same  as  under  ordinary  conditions, 
permitting  the  use  of  the  oil  immersion  lens. 

\ 

To  cover  top  of  Incubator  we  furnish  a  piece  of  clear  Mica  having  a 
hole  cut  in  center  through  which  the  lens  is  passed  when  making  adjust- 
ment for  the  bottom,  slide.  A  rubber  washer  slipped  over  the  lens  is  pro- 
vided for  sealing  the  opening  between  the  lens  and  mica.  (See  illustration.) 
By  this  arrangement  a  perfect  incubating  chamber  is  obtained  where 
bacteria  may  be  observed  for  any  length  of  time. 

The  Incubator  is  complete  in  every  detail  with  heating  element,  ther- 
mometer and  adjustable  electro-thermostat,  which  automatically  main- 
tains a  constant  temperature  inside  the  incubating  chamber,  as  long  as  the 
electric  current  is  on.  This  device  can  be  adjusted  for  any  temperature 
between  80  and  110  degrees  Fahrenheit  and  is  very  accurate. 

To  operate,  simply  screw  the  current  tap  with  its  lamp  into  any  110- 
volt  electric  lamp  socket  and  turn  on  the  current. 

Incubator  answers  all  the  requirements  that  a  warming  stage  should 
have.  In  the  Widal  test  for  typhoid  it  may  be  used  to  great  advantage.  It 
is  particularly  well  adapted  for  observation  of  Plant  micro-organisms, 
such  as  bacteria  and  yeasts  in  a  hanging  drop,  or  a  hanging  Agar  block; 
also  for  observation  of  Microscopic  animal-organisms  such  as  Malarial 
Parasites,  Trypanosomes  and  Amoeba. 

A  number  of  diseases  found  in  all  tropical  countries  cannot  be  properly 
examined  without  a  Warm  Stage. 


For  cultivation  of  Spirochetes  and  tumor  cells  by  the  recent  methods 
of  Harrison,  Noguchi  and  others,  this  apparatus  has  no  equal.

6140  Electrically  Heated  "Warm  Stage"  for  the  Microscope.  Our  electrically  heated 
"Warm  Stage"  is  the  only  appliance  of  its  kind  now  on  the  market.  It  will 
be  found  most  compact  and  convenient  and  always  ready  for  use,  as  it  fits 
the  stage  of  any  microscope  without  adjustment. 

To  operate,  simply  screw  the  current  tap  with  its  lamp  into  any  110- 
volt  electric  lamp  socket  and  turn  on  the  current. 

The  Warm  Stage  measures  8^2  inches  in  diameter  x  J/2  inches  in  thick- 
ness and  has  a  54-inch  hole  in  the  center  over  which  the  regular  micro- 
scopic glass  slide  may  be  placed. 

It  is  complete  in  every  detail  with  heating  element,  thermometer  and 
adjustable  electro-thermostat  that  automatically  maintains  a  constant  tem- 
perature on  the  top  of  the  disc,  as  long  as  the  electric  current  is  turned  on. 
With  this  Warm  Stage,  micro-organisms  requiring  blood  heat  temperature 
(98°  Fahrenheit)  for  maintaining  their  motility,  can  be  readily  discovered 
and  examined. 

The  most  important  purposes  for  which  the  Warm  Stage  may  be  used, 
among  others,  are  as  follows: 

a.  To  determine  if  a  case  of  dysentery  is  of  amoebic  variety,  Entamoeba 
Dystenteriae   (Histolytica).    The  stools  or  scrapings  from   the  rectum 
are  searched  on  the  Warm  Stage  for  living  moving  Amoeba. 

b.  To  search  for  Plasmodium,  Plasmodium  Malarae,  in  the  fresh  prepara- 
tion of  patient's  blood  in  the  diagnosis  of  suspected  Malaria. 

c.  To  ascertain   if  the  fresh  Spermatozoa  is  alive.    This  is  of  particular 
value  in  the  Medico-legal  cases. 

d.  To  discover  the  presence  of  Amoeba,  Entamoeba  Buccalis,  in  suspected 
cases  of  Pyorrhea  Alveolaris. 

When  it  is  desired  to  examine  a  large  area  the  Warm  Stage  is  most 
practical.  This  device  is  intended  to  supplant  the  old,  cumbersome  hot 
water  warm  stage.  It  is  light,  compact  and  convenient.  It  relieves  the 
operator  of  all  worry  as  to  its  positive  efficiency. 

The   illustration   shows   the   application    of   the   "Warm   Stage"   to   the 
microscope  .^  table.

6142  THELCO  LOW  TEMPERATURE  INCUBATOR.  Constant  temperature  in  the 
Thelco  Incubator  is  maintained  by  circulation  of  cool  air  around  the  nar- 
row water  jacket  of  the  incubator  chamber.  The  cool  air  is  admitted  from 
the  ice  chamber  through  a  shutter  operated  by  a  milled  head  screw  on  the 
outside.  This  shutter  is  adjusted  to  maintain  a  cool  air  temperature  slightly 
below  that  required  and  the  electric  heating  plate  under  the  water  jacket 
brings  the  chamber  to  the  right  temperature.  A  Thelco  spiral  bimetallic 
regulator  controls  the  heating  plate.  This  method  maintains  a  uniform 
temperature  throughout  the  chamber  and  is  very  economical  of  ice.  In 
ordinary  weather  a  single  supply  of  ice  will  last  several  days.  Although 
designed  primarily  for  gelatine  culture  cultivatipns  at  20°  C,  the  incubator 
can  be  used  just  as  satisfactorily  at  any  predetermined  temperature  from, 
about  10°  C.  to  40"  C,  or  at  temperatures  below  10°  C.  by  using  a  suitable 
cooling  mixture. 

The  heating  plate  is  a  wire-wound  resistance,  readily  removable  and 
controlled  by  the  strong  but  sensitive  Thelco  regulator,  which  maintains 
the  temperature  constant  to  1°  C.  A  switch  for  turning  on  and  off  the 
current  and  a  pilot  lamp  are  mounted  on  top  of  the  apparatus. 

The  incubator  chamber  is  double-walled,  of  heavy  copper  and  pro- 
vided with  three  perforated  shelves,  which  may  be  placed  at  any  desired 
height.  It  has  a  felt-cushioned,  glass  door,  which  is  air-tight.  The  cabinet 
is  of  wood,  insulated  with  felt  and  dead  air-spaces,  making  in  all  10  walls. 
It  is  entirely  sheathed  in  steel  plate,  handsomely  finished  in  white 
porcelain,  with  polished  aluminum  trimmings.  The  incubator  is  mounted 
on  a  heavy  iron  base.  Size,  46  inches  high,  38  inches  wide,  31  inches

6186  MICROSCOPE — Spencer^  Lens  Co.  No.  64.  This  microscope  has  proven  a 
standard  of  its  own.  It  is  exceedingly  desirable  for  general  biology  and  is 
in  daily  use  in  hundreds  of  laboratories. 

The  Body  Tube  is  our  standard,  37  m.m.  in  diameter,  taking  standard 
objectives  and  oculars. 

The  Arm  and  its  Side  Fine  Adjustment  "D"  are  identical  with  Micro- 
scope No.  44.  This  adjustment  is  patented,  is  exceedingly  durable,  will  with- 
stand very  hard  usage  and  not  develop  lost  motion.  (See  description  and 
diagram  illustration  under  No.  44.)  It  travels  laterally,  giving  an  instant 
visible  index  of  the  position  of  the  adjustment  relative  to  the  total  excur- 
sion. Steel  pins  in  heads  of  buttons  produce  an  absolute  stop  at  either 
end  of  excursion,  preventing  jamming  or  binding  of  screw.  There  are 
but  two  bearing  surfaces  and  three  working  parts.  The  main  bearing  is 
made  of  one  single  piece.  One  revolution  moves  the  tube  .2  mm.  Ad- 
justment ceases  to  work  when  objective  comes  in  contact  with  slide. 

The  .Stage,  112x108  mm.,  is  completely  covered  with  vulcanite  rubber, 
vulcanized  directly  to  the  stage  plate.  Beneath  the  stage  is  an  iris  dia- 
phragm operated  by  a  knurled  wheel,  62  mm.  in  diameter.  Abbe  Con- 
denser is  supplied  when  ordered,  and  is  fitted  in  a  simple,  spiral  focusing 
substage  ring.  Distance  is  80  mm.  from  optical  center  to  arm. 
Furnished  in  hardwood  cabinet,  lock  and  key.

6188  MICROSCOPE,  Spencer  Lens  Co.,  No.  44-H.  This  instrument  has  pnoven  the 
most  popular  of  all  Spencer  Microscopes.  Many  hundred  are  in  daily 
use,  in  medical  and  general  laboratories,  also  by  physicians.  This,  we 
believe,  is  the  best  microscope  value  on  the  market. 

The  Body  Tube  is  standard,  taking  standard  objectives  and  oculars. 

The  Arm  is  strong  and  very  graceful,  fitted  with  Side-Fine  Adjustment 
and  possessing  many  exclusive  features.  It  has  but  two  bearing  surfaces 
and  three  working  parts.  The  patented  one-piece  construction  bearing 
carries  the  solid  steel  screw.  This  screw,  with  no  less  than  twenty  threads 
engaged  even  at  the  limit  of  its  motion,  has  a  heavy  flange,  F,  working 
against  the  level,  L.  When  the  screw  is  turned  in  snch  a  direction  as  to 
carry  F  forward,  the  lever  is  so  swung  as  to  raise  the  body  tube.  The 
reverse  motion  permits  the  tube  to  be  lowered  under  the  influence  of 
the  spring,  The  focusing  buttons  at  either  end  of  this  screw  travel 
laterally  and  serve  as  a  visible  index  of  the  center  of  the  fine  adjustment 
action.  Steel  pins  in  the  heads  form  positive  stops  at  either  end  of 
the  excursion.  The  direction  in  focusing  is  the  same  with  both  fine 
and  coarse  adjustments.  One  revolution  moves  tube  .2  mm. 

The  Stage,  112x108  mm.,  is  completely  covered  with  genuine  vulcanite 
rubber,  vulcanized  directly  to  the  stage  plate.  Distance  is  80  mm.  from 
optical  axis  to  arm. 

The  Substage  is  standard  quick-screw  form. 
Furnished  in  hardwood  cabinet,  lock  and  key. 

Equipped  with  Huyghenian  Oculars  6x  and  lOx,  objectives  16  mm.  (2/3"),

6194     MECHANICAL    STAGE,    Spencer    Lens    Co.      The    most    popular    mechanical 
stage  yet  produced;  attachable  to  any  modern  square  staged  microscope. 

A  stop  at  the  front  always  insures  its  return  to  the  same  position  on  the 
microscope  stage.  Should  work  be  interrupted  and  the  mechanical  stage 
be  removed,  when  replaced,  the  object  of  interest  may  readily  be  found, 
providing  the  vernier  readings  have  been  noted.  The  vernier  of  the  lateral 
movement  is  placed  slightly  to  one  side  of  the  arm  of  the  microscope  where 
it  may  easily  be  read. 

The  movements  are  by  diagonal  rack  and  pinion,  and  are  firm  and  reliable, 
permitting   the    most    delicate    adjustments.      The    range    of   movement    is 
ample  to  cover  the  entire  area  of  the  standard  slide,  1x3  inches.

MICROSCOPIC  CABINET,  Minot's  Metal  Cabinet.  This  cabinet,  designed 
by  Dr.  Chas.  S.  Minot,  is  very  compact,  occupying  much  less  space  than 
a  wooden  cabinet  and  affording  better  protection  against  fire.  It  is 
strongly  made  of  metal  throughout,  neatly  finished  on  the  outside  in 
maroon-colored  japan  with  bronze  stripes.  The  inside  finish  is  in  black 
japan.  It  contains  thirty  japanned  metal  trays,  each  holding  twenty-four 
glass  slides,  75x25  mm.  The  trays  are  provided  with  convenient  knobs  and 
with  card  holders.  The  new,  improved  construction  of  the  trays  holds  each 
slide  independently  in  its  place,  preventing  shaking  or  slipping  of  slides 
when  trays  are  removed  The  cabinet  is  furnished  with  a  good  brass  lock, 
and  measures  36.5  cm.  in  height,  32.5  cm.  in  depth,  and  17.5  cm.  in  width, 
outside.  Capacity  seven  hundred  and  twenty  slides.

6334  MICROTOME,  Ether  Freezing  Attachment,  Spencer  Lens  Co.  This  freez- 
ing attachment  consists  of  a  freezing  chamber  of  hard  rubber  which  so 
prevents  the  radiation  of  the  cold  that  the  tissue  is  quickly  frozen. 
It  will  freeze  tissue,  15  mm.  in  diameter  and  3  mm.  thick,  in  one 
minute,  using  only  5  cc.  of  ether. 

The  ether  is  held  in  the  metal  tank,  which  for  filling  may  be  unscrewed 
from  the  support  from  which  it  is  suspended.  Any  excess  of  ether 
which  does  not  evaporate  is  drained  back  into  the  metal  chamber 
from  which  it  came.  There  are  no  bottles  or  entangling  tubes  and 
no  waste  of  ether.  It  is  simple,  compact  and  efficient.  It  can  be 
used  on  any  sliding  microtome $7.50

6336     MICROTOME  Freezing  Attachment,  for  use  with  Carbonic  Acid. 

The  superior  qualities  of  this  freezing  chamber  have  been  well  recog- 
nized during  the  past  ten  years.  It  is  substantially  made,  easy  to  operate 
and  eminently  efficient.  There  is  a  hard  rubber  non-conducting  ring  (the 
suggestion  of  Dr.  L.  D.  Wilson  of  St.  Mary's  Hospital,  Rochester,  Minn.) 
between  the  corrugated  plate  to  which  the  object  is  frozen  and  the  rest 
of  the  apparatus.  This  prevents  the  conduction  of  the  cold  from  the  speci- 
men to  the  other  parts,  thus  saving  time  and  gas. 

This  freezing  attachment  may  be  used  with  Microtomes  Nos.  6338  and  40.

cutting  celluloidin  or  frozen  sections,  may  also  be  used  for  paraffine 
sections  and  can  be  adjusted  for  any  thickness  of  cut. 
This  peculiar  motion  of  the  knife  makes  this  microtome  especially  desirable 
for  cutting  frozen  sections,  and  when  used  with  our  CO2  freezing  chamber 
it  has  no  equal.  Sections  may  be  cut,  stained  and  mounted  in  one  and 
one'-half  minutes  from  the  time  the  tissue  is  placed  on  the  freezing  plate.

6343  MICROTOME — Spencer  Lens  Co.,  No.  820.  The  Spencer  Rotary  Microtome  is 
an  original  construction.  It  is  intended  for  the  most  accurate  and  careful 
work.  An  inclined  plane  feed,  which  is  independent  of  the  up-and-do.wn 
movement  on  the  perpendicular  support,  overcomes  the  inaccuracies  inher- 
ent in  other  rotary  microtomes.  The  most  important  element  in  a  micro- 
tome is  an  accurate  and  reliable  feed  mechanism.  This,  and  rigidity,  are 
vital.  These  points  are  paramount  in  this  instrument. 

The  feed  is  so  arranged  that  it  can  be  set  for  sections  of  any  thickness, 
from  1  micron  to  60  microns,  by  turning  the  knurled  button  at  the  back 
of  the  case  until  the  number  representing  the  desired  thickness  appears 
opposite  the  indicator  at  the  small  opening  in  the  side  of  the  case  near  the 
balance  wheel. 

The  total  excursion  of  the  feed  is  37  mm.,  allowing  a  sufficient  range 
for  cutting  a  complete  series  of  a  very  large  object  without  the  necessity 
of  a  break  due  to  resetting  the  knife  and  feed  mechanism. 

The  object  clamp  is  a  part  of  a  ball  which  fits  into  its  socket  so 
uniquely  that  it  is  clamped  as  solidly  as  though  it  and  its  socket  were  one 
piece.  The  object  is  easily,  accurately  and  delicately  oriented  to  any  de- 
sired angle.  The  angle  can  be  changed  in  any  plane  without  interfering 
with  any  angle  already  attained  in  another  plane.  The  object  may  easily 
be  rotated. 

The  up-and-down  stroke  of  the  object  clamp  is  50  mm.,  which  permits 
the  cutting  of  very  large  sections  and  gives  sufficient  stroke  for  celloidin 
cutting. 

The  knife  is  fastened  by  two  clamps,  each  of  which  clamps  the  knife 
at  the  back  and  along  \Y$  inches  of  the  edge  as  well.  It  may  be  turned  to 
any  desired  angle,  and  the  clamps  may  also  be  moved  toward  one  another 
to  bring  them  as  near  to  the  ribbon  as  desired  to  gain  additional  rigidity. 
When  the  clamps  are  thus  drawn  together,  the  knife  may  be  moved  so  that 
practically  all  of  the  cutting  edge  can  be  used  before  the  necessity  of 
resharpening.  The  adjusting  screws  provide  for  knives  of  different  widths. 
The  balance  wheel  is  grooved,  so  that  the  instrument  may  be  run  by  a 
motor.

6418  SLIDE  WARMER,  Electric,  to  provide  a  convenient  method  of  mounting 
paraffin  sections.  The  slides  are  heated  slowly  and  evenly  over  their 
entire  extent  to  a  temperature  just  below  the  melting  point  of  the 
paraffin,  thereby  giving  maximum  flattening  without  damage  to  the 
specimen.  Forty  slides  can  be  accommodated  at  one  time.  A  ther- 
mometer is  placed  just  below  the  block  of  transite  and  registers  a 
temperature  somewhat  lower  than  that  on  the  surface.  With  paraffin 
of  55°  the  best  results  are  obtained  when  the  regulator  is  set  to  main- 
tain a  thermometer  'temperature  of  43°.  The  slides  are  protected 
from  dust  while  drying  by  a  metal  hood  which  is  placed  over  the 
apparatus.  With  this  slide  warmer  drying  is  cut  down  from  24  hours 
at  room  temperature  to  2  or  3  hours  at  a  temperature  just  under  the 
paraffin  melting  point.  Price,  complete.. $35.00

6422  ELECTRIC  STERILIZERS  or  Drying  Ovens.  The  frame  work  of  our 
Sterilizers  are  made  of  steel,  with  bodies  of  transite  and  fittings  of 
lacquered  brass.  Electric  Sterilizer  is  made  with  double  walls  of 
transite,  with  an  intervening  dead  air  space  and  is  furnished  with 
double  doors,  thus  insuring  perfect  insulation.  It  is  constructed  to 
maintain  temperatures  of  from  60  to  200  degrees  Centigrade,  with  a 
maximum  current  consumption  of  approximately  nine  amperes. 

The  inside  dimensions  are:    Height,  10  inches;  width,  18  inches; 
/  depth,  10  inches.    It  has  two  removable  shelves  and  will,  therefore, 

accommodate  glass  apparatus  of  various  sizes. 

The  Heating  Medium  consists  of  six  self-contained  wire  units, 
which  are  wound  on  natural  lava  stones,  thus  preventing  crumbling 
and  disintegration,  with  greatly  increased  stability  of  the  unit.  The 
units  can  be  easily  removed  with  the  aid  of  a  screwdriver  and  re- 
placed with  new  ones,  should  they  burn  out.  A  pilot  lamp  is  pro- 
vided to  indicate  when  the  current  is  on  or  off. 

The  heating  units  are  governed  by  a  controller  and  thermo-regu 
lator,  the  operating  screws  of  which  are  located  on  the  side  of  the 
Sterilizer  near  the  bottom.  These  afford  means  of  utilizing  two  or 
more  of  the  units  at  a  time,  as  occasion  may  require.  The  elec- 
trical connections  are  complete,  including  special  six-foot  cord,  with 
snap  switch,  ready  for  instant  connection.  Chemical  thermometer 
included. 

Owing  to  the  amount  of  current  (9  amperes)  required  to  operate 
this  Sterilizer  at  its  maximum  heat,  special  provision  must  be  made 
for  an  electric  circuit  other  than  the  ordinary  light  circuit.  Weight, 
packed  for  shipment,  85  pounds.  Price,  complete  as  per  cut $110.00

LABORATORY  TABLE 

The  Laboratory  necessitates  the  use  of 
an  assortment  of  various  apparatus,  chemi- 
cals, glassware,  etc.,  that  always  take  up 
valuable  space  and  usually  consume  time  in 
assembling,  whenever  a  test  is  to  be  made. 

To  facilitate  the  work  in  the  Laboratory, 
we  have  designed  a  compact  Laboratory 
Table,  with  a  place  for  everything,  thus 
eliminating  time  usually  spent  in  looking 
for  things,  or  in  connecting  or  disconnect- 
ing electrical  apparatus,  that  are  being  used. 

General   Description. 

The  Cabinet  is  made  horn  selected  quar- 
ter-sawed oak,  with  a  massive  and  substan- 
tial construction.  It  is  finished  in  light  oak 
with  the  finest  high  grade  hand-rubbed  fin- 
ish. The  top  of  the  working  table  is  fin- 
ished in  the  customary  acid-proof  black. 
The  dimensions  over  all  are:  height  56", 
width  56",  depth  33".  Size  of  working 
space,  5524"xl8".  Height  from  floor  30". 
The  upper  part  of  the  cabinet  is  divided 
into  two  equal  compartments,  each  20^4" 
high  x  25l/z"  wide  x  31J4"  deep  and  provided 
with  two  adjustable  shelves.  Specially 
constructed  roller  curtains,  easily  closed  or 
A  hole  3"  in  diameter  is  provided  in  the 

right  hand  corner  of  the  second  compartment,  permitting  the  convenient  disposal  of 
refuse  into  a  jar.  placed  on  a  small  shelf  in  the  compartment  belo^.  The  lower 
part  of  the  cabinet  has  two  compartments,  each  25"  high  x  15"  wide  x  30"  deep, 
equipped  with  doors.  The  right  hand  compartment  is  provided  with  an  exceptionally 
solid,  stationary  shelf  intended  to  support  a  Centrifuge.  The  space  below  this  shelf 
as  well  as  the  left  hand  side  compartment  are  jntended  for  storage  purposes  of 
glassware,  etc.  There  are  two  drawers,  each  2^2"  high  x  8^"  wide  x  2124"  deep. 
One  of  them  is  divided  into  several  small  compartments  while  the  other  one  is 
without  divisions.  All  compartments  and  drawers  are  furnished  with  locks  and  keys, 
thus  preventing  tampering. 

ATTACHMENTS   AND   ACCESSORIES 

A  porcelain  sink,  7  inches  in  diameter  by  6J^  inches  deep,  is  furnished  together 
wtih  a  gooseneck  faucet.  Water  and  gas  connections  are  provided  and  arranged  so 
that  every  convenience  is  offered  the  operator.

A  Burette  Holder  is  also  furnished.  This  holder  is  attached  to  the  side  of  the 
dividing  partition  in  the  upper  part  of  the  Cabinet.  It  may  be  removed,  when  not 
in  use,  so  as  not  to  interfere  with  the  closing  of  the  roller  curtain.  The  Burette 
is  held  in  position  by  an  easily  adjusted  spring,  permitting  adjustment  both  hori- 
zontally and  vertically. 

Electrical  Connections.  The  table  is  wired  for  electricity.  A  push  switch,  located 
on  the  right  hand  side,  cuts  off  the  electric  current  to  the  entire  table.  Four  Edison 
Base  Sockets  installed  conveniently  at  the  right  hand  corner  of  the  working  space, 
afford  connections  for  the  electrical  apparatus  required.  A  special  socket  in  the  lower 
right  hand  compartment  provides  connection  for  a  centrifuge. 

An  adjustable  Desk  Light  is  installed  at  the  top  of  the  Cabinet,  directly  over  the 
dividing  partition.  This  light  is  provided  with  a  separate  switch. 

In  the  center  of  the  table,  in  a  position  most  appropriate  for  the  use  of  a  micro- 
scope, there  is  embedded  an  electric  microscope  lamp,  covered  with  approved  daylight 
glass.  A  convenient  push  switch  is  provided  for  this  lamp.  When  not  in  use  the 
daylight  glass  is  protected  by  a  hinged  metal  cover,  which  folds  down  flush  with  the  top 
of  the  table. 

An  electric  cord  wtih  attachment  plug  is  also  furnished  and  the  table  may  be 
attached  to  any  electric  light  socket  without  danger  of  burning  out  the  fuse. 

MANUAL 

In  order  to  enable  the  physician  to  more  accurately  perform  the  laboratory  tests, 
essential  to  clinical  diagnosis,  we  furnish  a  complete  working  manual  with  each  table.

6456  Muencke's  Improved  Thermo-Regulator  for  low  pressure  only.  In  this 
regulator  a  stopcock  controls  the  passage  of  gas  through  the  horizontal 
tube  to  the  reserve  flame.  When  the  temperature  rises  the  gas  supply 
is  reduced  by  the  mercury  closing  the  passage  at  the  fork » $7.50

6460  Dunham's  Thermo-Regulator.  This  is  an  extremely  sensitive  regulator  in 
which  the  sensitiveness  is  derived  from  a  large  alcohol  bulb.  The 
minute  changes  in  the  volume  of  the  alcohol  as  caused  by  the  varia- 
tions in  temperature  act  upon  a  U-shaped  column  of  mercury  and 
control  the  volume  of  gas  which  passes  through"  the  tubes  Adjust- 
ments for  the  different  temperatures  to  be  maintained  are  made  by 
sliding  the  gas  inlet  tube  upward  or  downward  as  required.  The 
thermostat  is  furnished  complete  with  liquid  and  mercury  for  rilling.

maximum  flow  of  gas,  which  is  ample  for  high  temperatures,  may  be 
reduced  to  an  amount  just  sufficient  to  keep  the  flame  from  going  out. 
When  used  in  connection  with  the  gas  pressure  regulator,  Merrill's,  it 
will  be  found  to  work  to  the  greatest  satisfaction $10.00

6466  THERMOSTAT,  Pencil  Type.  The  Thermostat  shown  herewith  is  used  for 
controlling  temperatures  of  liquids.  It  consists  of  a  thin  copper  tube 
hermetically  closed  at  the  bottom  end,  so  that  it  may  be  partly  immersed 
in  liquids  without  damage  to  the  interior.  A  sensitive  bimetallic  bar 
extends  from  the  bottom  half  way  up  the  tube 

The  range  of  the  Thermostat  is  from  30  to  80  degrees  Centigrade. 
A    special    condenser   is   mounted    inside   the    tube.     The  .condenser   kills 
the  electric  spark  when  the  contact  points  are  separated,  thus  protecting 
same  against   destruction,  provided  the   electric   current  does  not  exceed 
1  ampere. 

The  dimensions  of  the  Thermostat  are:     6  inches  in  length  x  54-inch  in 
diameter.

6468     Combination  Electric  Heater  and  Pencil  Type  Thermostat  for  Heating  and  Con- 
trolling Temperature  of  Liquids  in  Water  Baths. 

The  apparatus  consists  of  a  heating  disc,  measuring  five  inches  in  diam- 
eter by  one-half  inch  in  thickness  and  an  adjustable  pencil  type  electro- 
themostat,  measuring  six  inches  in  length  by  five-eighths  of  an  inch  in 
diameter,  together  with  a  pilot  lamp  indicating  when  the  current  is  on 
or  off. 

They  are  mounted  together  and  are  self-contained,  with  a  six-foot  cord 
and  attachment  plug,  which  may  be  connected  to  any  110-volt  electric  light 
socket. 

Constant  water  level  in  the  bath  is  desirable  for  best  results;  water  bath 
heater  provides  for  the  maintenance  of  any  temperature  between  35  de- 
grees and  60  degrees  Centigrade  in  any  suitable  utensil.  It  is  not  necessary 
to  use  a  water  bath  as  shown  in  the  illustration.  The  apparatus  can  be 
applied  to  any  water  bath  where  the  maximum  capacity  of  water  does 
not  exceed  two  quarts.

DESCRIPTION 

This  Pattern  Wasserman  Bath  which  has  been  adopted  as  the  Standard  for  the 
United  States  Army,  is  most  economical  in  operation. 

The  Water  Vessel  which  measures  30"x23"xl2"  deep,  on  the  standard  size,  per- 
mits the  use  of  a  very  large  volume  of  water.  Being  surrounded  by  a  Case  of 
Polished  Rust  Resisting  Iron,  lined  with  a  heavy  layer  of  asbestos,  the  water  holds 
its  temperature  with  the  minimum  expenditure  of  heat.  A  single  Micro  burner  being 
sufficient  for  this  large  bath  when  gas  is  used. 

The  only  part  exposed  to  the  air  is  the  lid. 

The  Lid  is  made  double  the  outer,  or  top  being  flat,  the  inner  lid  sloping  to  rear. 
The  condensation  which  forms  on  the  outer  lid  falls  on  the  inner  lid,  flowing  to 
the  two  rear  corners  prevents  any  dripping  of  water  into  the  Tubes  from  injuring 
the  specimens  being  tested. 

There  is  furnished  with  each  bath  a  Thermometer,  also  a  Gas  Thermo  Regulator 
and  two  Micro  Burners. 

The  Constant  Level  which  maintains  the  correct  height  of  water  in  the  bath  is 
very  simple,  and  easily  connected  with  two  rubber  hose,  one  from  the  water  supply 
and  the  other  to  the  waste  pipe.  The  use  of  this  feature  is  optional.  The  amount  of 
water  evaporated  being  very  little. 

When  Electric  Equipment  is  ordered  with  this,  we  furnish  an  Electro  Regulator 
of  the  best  make  and  all  necessary  connections,  Lamp  Switch,  etc.,  to  use  on  either 
110  or  220  volts. 

The  racks  furnished,  20  in  number,  are  marked  from  1  to  200,  are  the  Standard 
Army  Medical  School  Wasserman  Type.

ished outside,  having  a  spe- 
cially constructed  Double 
Lid  the  inner  one  of  which 
slopes  toward  the  rear,  pre- 
venting any  dropping  of  the 
Condensation  of  the  Sera 
being  tested. 

The  Thermometer  Holder 
is  so  arranged  that  the  Ther- 
mometer maintains  its  up- 
right position  at  all  times,

Laboratory  Utensils 


LABORATORY  service  requires 
substantial  utensils  which  i  re  not 
subject  to  deterioration — which  will 
not  corrode  nor  affect  the  chemicals 
being  handled.  That  Duriron  has  suc- 
cessfully met  these  requirements  is 
evidenced  by  its  continued  use  in  the 
laboratories  of  prominent  chemical 
plants  and  colleges  of  the  country. 
The  illustration  examples  only  a  few 
such  utensils — we  will  gladly  send  you 
details,  or  a  sample  laboratory  dish 
free  —  you  can  be  your  own  judge  of 
Duriron's  characteristics. 


We  also  manufacture  Sinks  for  laboratory  uses, 
Pipe,  Fittings,  Valves,  Cocks,  Pumps,  Steam 
Syphons,  Exhaust  Fans,  Jacketed  Kettles, 
Pots,  Towers,  Jets,  Condensers,  Manifolds,  Stir-

Evaporator 


Largest  double  effect  in  use  today  for  hide  glue  liquor.    Standard  Swenson  horizontal  tube 
type.    Over  80  per  cent  of  the  glue  made  in  the  U.  S.  A.  is  concentrated  in  this  type  evap- 
orator which  turns  out  the  strongest  and  lightest  colored  glue. 

Single  and  multiple  effects  for  handling  any 
liquor  in  commercial  quantities.  Sizes  reg- 
ularly range  from  100  to  10,000  gallons  of 
evaporation  per  hour.  We  manufacture  five 

standard  types,  although  when  these  do  not  meet 
the  requirements  we  construct  combinations  of  these 
types  or  special  types  to  produce  the  desired  results. 
We  frequently  find  it  necessary  to  employ  some 
special  material  of  construction  such  as  aluminum 
or  bronze  or  tile  or  lead. 

Specialists 

Swenson  engineers  are  specialists  in  evaporation  and 
all  reclaiming  machinery — which  includes  vacuum 
pans,  leaching  batteries,  beet  sugar  machinery,  pulp 
mill  machinery,  special  chemical  and  waste  product 
machinery.

and  tables  will  be  mailed  gratis  to  responsible  parties 
showing  their  business  or  collegiate  connection,
